# Phase 3 — Advanced Features Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Build sharing, subscriptions, notifications, profile settings, onboarding wizard, summary metrics with charts, and task report PDF download.

**Architecture:** A shared foundation layer (hooks, settings hub, notification bell) is built first, then 5 domain agents run concurrently on independent feature areas. Each agent produces pages and components that compile independently.

**Tech Stack:** Next.js 16 (App Router), TanStack Query v5, React Hook Form + Zod 4, shadcn/ui + Radix, Tailwind CSS 4, Recharts (new), Zustand, Lucide icons.

---

## Execution Strategy: 7 Tasks, 5 Run in Parallel

```
Task 1: Shared Foundation (sequential — all features depend on this)
    ↓
Task 2: Sharing (residence + contractor)  ─┐
Task 3: Profile Settings                   ─┤
Task 4: Notifications + Subscription       ─┤  ← 5 parallel agents
Task 5: Onboarding Wizard                  ─┤
Task 6: Dashboard + Task Reports           ─┘
    ↓
Task 7: Integration + Verification (sequential — cross-feature wiring)
```

**Verification gate:** Each task ends with `npm run build`. No task is complete until it compiles clean.

---

## Task 1: Shared Foundation

**Files:**
- Create: `src/lib/hooks/use-notifications.ts`
- Create: `src/lib/hooks/use-subscription.ts`
- Create: `src/components/notifications/notification-bell.tsx`
- Create: `src/app/app/settings/layout.tsx`
- Modify: `src/app/app/settings/page.tsx` (overwrite stub → settings hub)
- Modify: `src/components/layout/top-bar.tsx` (add notification bell)
- Modify: `src/lib/hooks/index.ts` (add new hook exports)

### Step 1: Install Recharts

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web
npm install recharts
```

### Step 2: Create notification hooks

```typescript
// src/lib/hooks/use-notifications.ts
"use client";

import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import * as notificationsApi from '@/lib/api/notifications';
import type { UpdatePreferencesRequest } from '@/lib/api/notifications';

export function useNotifications(limit?: number) {
  return useQuery({
    queryKey: ['notifications', limit],
    queryFn: () => notificationsApi.listNotifications(limit),
  });
}

export function useUnreadCount() {
  return useQuery({
    queryKey: ['notifications', 'unread-count'],
    queryFn: () => notificationsApi.getUnreadCount(),
    refetchInterval: 60_000, // Poll every minute
  });
}

export function useNotificationPreferences() {
  return useQuery({
    queryKey: ['notifications', 'preferences'],
    queryFn: () => notificationsApi.getPreferences(),
  });
}

export function useUpdatePreferences() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (data: UpdatePreferencesRequest) => notificationsApi.updatePreferences(data),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['notifications', 'preferences'] });
    },
  });
}

export function useMarkAsRead() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (id: number) => notificationsApi.markAsRead(id),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['notifications'] });
      queryClient.invalidateQueries({ queryKey: ['notifications', 'unread-count'] });
    },
  });
}

export function useMarkAllAsRead() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: () => notificationsApi.markAllAsRead(),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['notifications'] });
      queryClient.invalidateQueries({ queryKey: ['notifications', 'unread-count'] });
    },
  });
}
```

### Step 3: Create subscription hooks

```typescript
// src/lib/hooks/use-subscription.ts
"use client";

import { useQuery } from '@tanstack/react-query';
import * as subscriptionApi from '@/lib/api/subscription';

export function useSubscriptionStatus() {
  return useQuery({
    queryKey: ['subscription', 'status'],
    queryFn: () => subscriptionApi.getSubscriptionStatus(),
  });
}

export function useFeatureBenefits() {
  return useQuery({
    queryKey: ['subscription', 'features'],
    queryFn: () => subscriptionApi.getFeatureBenefits(),
    staleTime: Infinity,
  });
}

export function useUpgradeTriggers() {
  return useQuery({
    queryKey: ['subscription', 'upgrade-triggers'],
    queryFn: () => subscriptionApi.getAllUpgradeTriggers(),
    staleTime: Infinity,
  });
}
```

### Step 4: Create NotificationBell component

```tsx
// src/components/notifications/notification-bell.tsx
"use client";

import { useState } from "react";
import { Bell } from "lucide-react";
import { Button } from "@/components/ui/button";
import {
  DropdownMenu,
  DropdownMenuContent,
  DropdownMenuItem,
  DropdownMenuSeparator,
  DropdownMenuTrigger,
} from "@/components/ui/dropdown-menu";
import { Badge } from "@/components/ui/badge";
import { useNotifications, useUnreadCount, useMarkAsRead, useMarkAllAsRead } from "@/lib/hooks/use-notifications";

export function NotificationBell() {
  const { data: unreadData } = useUnreadCount();
  const { data: notifData } = useNotifications(10);
  const markAsRead = useMarkAsRead();
  const markAllAsRead = useMarkAllAsRead();
  const unreadCount = unreadData?.unread_count ?? 0;

  return (
    <DropdownMenu>
      <DropdownMenuTrigger asChild>
        <Button variant="ghost" size="icon" className="relative">
          <Bell className="size-5" />
          {unreadCount > 0 && (
            <span className="absolute -top-1 -right-1 flex size-5 items-center justify-center rounded-full bg-destructive text-[10px] font-bold text-destructive-foreground">
              {unreadCount > 9 ? "9+" : unreadCount}
            </span>
          )}
        </Button>
      </DropdownMenuTrigger>
      <DropdownMenuContent align="end" className="w-80 max-h-96 overflow-y-auto">
        <div className="flex items-center justify-between px-3 py-2">
          <p className="text-sm font-semibold">Notifications</p>
          {unreadCount > 0 && (
            <Button variant="ghost" size="sm" className="text-xs h-auto py-1" onClick={() => markAllAsRead.mutate()}>
              Mark all read
            </Button>
          )}
        </div>
        <DropdownMenuSeparator />
        {(!notifData || notifData.results.length === 0) ? (
          <div className="px-3 py-6 text-center text-sm text-muted-foreground">No notifications</div>
        ) : (
          notifData.results.map((n) => (
            <DropdownMenuItem key={n.id} className="flex-col items-start gap-1 py-2"
              onClick={() => { if (!n.is_read) markAsRead.mutate(n.id); }}>
              <p className={`text-sm ${n.is_read ? "text-muted-foreground" : "font-medium"}`}>{n.title}</p>
              <p className="text-xs text-muted-foreground">{n.body}</p>
              <p className="text-xs text-muted-foreground">{new Date(n.created_at).toLocaleDateString()}</p>
            </DropdownMenuItem>
          ))
        )}
      </DropdownMenuContent>
    </DropdownMenu>
  );
}
```

### Step 5: Modify TopBar to include notification bell

In `src/components/layout/top-bar.tsx`, add `<NotificationBell />` before the profile dropdown. Import from `@/components/notifications/notification-bell`.

Add a `<div className="flex items-center gap-2">` wrapper around the bell and avatar dropdown.

### Step 6: Create settings layout with sidebar navigation

```tsx
// src/app/app/settings/layout.tsx
"use client";

import Link from "next/link";
import { usePathname } from "next/navigation";
import { cn } from "@/lib/utils";
import { User, Bell, CreditCard } from "lucide-react";

const settingsNav = [
  { label: "Profile", href: "/app/settings/profile", icon: User },
  { label: "Notifications", href: "/app/settings/notifications", icon: Bell },
  { label: "Subscription", href: "/app/settings/subscription", icon: CreditCard },
];

export default function SettingsLayout({ children }: { children: React.ReactNode }) {
  const pathname = usePathname();

  return (
    <div className="space-y-6">
      <h1 className="text-2xl font-bold tracking-tight">Settings</h1>
      <div className="flex flex-col sm:flex-row gap-6">
        <nav className="flex sm:flex-col gap-1 sm:w-48 shrink-0">
          {settingsNav.map((item) => (
            <Link key={item.href} href={item.href}
              className={cn(
                "flex items-center gap-2 rounded-md px-3 py-2 text-sm font-medium transition-colors",
                "hover:bg-accent hover:text-accent-foreground",
                pathname === item.href ? "bg-accent text-accent-foreground" : "text-muted-foreground"
              )}>
              <item.icon className="size-4" />
              {item.label}
            </Link>
          ))}
        </nav>
        <div className="flex-1 min-w-0">{children}</div>
      </div>
    </div>
  );
}
```

### Step 7: Overwrite settings page stub → redirect to profile

```tsx
// src/app/app/settings/page.tsx
import { redirect } from "next/navigation";

export default function SettingsPage() {
  redirect("/app/settings/profile");
}
```

### Step 8: Update hooks barrel export

Add to `src/lib/hooks/index.ts`:
```typescript
export * from './use-notifications';
export * from './use-subscription';
```

### Step 9: Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Step 10: Commit

```bash
git add -A && git commit -m "feat: add Phase 3 foundation — notification hooks, subscription hooks, settings layout, notification bell"
```

## Task 2: Sharing (Residence + Contractor)

**Depends on:** Task 1

**Files:**
- Create: `src/app/app/residences/[id]/share/page.tsx`
- Create: `src/app/app/residences/join/page.tsx`
- Create: `src/components/sharing/share-code-display.tsx`
- Create: `src/components/sharing/user-management.tsx`
- Create: `src/components/sharing/honeydue-file-handler.tsx`
- Create: `src/lib/hooks/use-sharing.ts`
- Modify: `src/app/app/residences/[id]/page.tsx` (add Share button)
- Modify: `src/app/app/contractors/[id]/page.tsx` (add Share/Export button)
- Modify: `src/app/app/contractors/page.tsx` (add Import button)

### Residence Sharing Components

**share-code-display.tsx** — Displays share code with copy button and expiry countdown:
- If no active code: "Generate Share Code" button → calls `POST /residences/:id/generate-share-code/`
- If active code: displays code in large monospace text, copy-to-clipboard button, expiry timer
- Uses existing `residencesApi.generateShareCode()` and `residencesApi.getShareCode()`

**user-management.tsx** — Lists residence users with remove action:
- Uses `residencesApi.getResidenceUsers(id)` to fetch user list
- Each user row: name, email, role badge (Owner/Member)
- Owner can click "Remove" → ConfirmDialog → `residencesApi.removeResidenceUser(residenceId, userId)`

### .honeydue File Handler

**honeydue-file-handler.tsx** — Reusable component for both residence and contractor sharing:
- **Export mode**: Takes data object, generates JSON `{ type: "residence"|"contractor", ... }`, triggers browser download as `.honeydue` file
- **Import mode**: FileUpload drop zone accepting `.honeydue` files, reads JSON, validates type, calls callback with parsed data
- Uses `URL.createObjectURL` + anchor click for download
- Uses `FileReader.readAsText` for import

### Pages

**Residence Share page** (`/app/residences/[id]/share`):
- ShareCodeDisplay for generating/displaying share codes
- .honeydue export button → downloads file with share code embedded
- UserManagement table
- Only accessible to residence owner

**Residence Join page** (`/app/residences/join`):
- Text input for manual code entry
- .honeydue file import drop zone
- On submit: calls `residencesApi.joinWithCode()` → redirect to residence detail

### Contractor Sharing

On contractor detail page, add "Share" button → generates .honeydue file with contractor data for download.
On contractor list page, add "Import" button → opens import dialog → reads .honeydue file → creates contractor via API.

### Query hooks

```typescript
// src/lib/hooks/use-sharing.ts
"use client";

import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import * as residencesApi from '@/lib/api/residences';

export function useShareCode(residenceId: number) {
  return useQuery({
    queryKey: ['residences', residenceId, 'share-code'],
    queryFn: () => residencesApi.getShareCode(residenceId),
    enabled: !!residenceId,
  });
}

export function useGenerateShareCode(residenceId: number) {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: () => residencesApi.generateShareCode(residenceId),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['residences', residenceId, 'share-code'] });
    },
  });
}

export function useResidenceUsers(residenceId: number) {
  return useQuery({
    queryKey: ['residences', residenceId, 'users'],
    queryFn: () => residencesApi.getResidenceUsers(residenceId),
    enabled: !!residenceId,
  });
}

export function useRemoveResidenceUser(residenceId: number) {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (userId: number) => residencesApi.removeResidenceUser(residenceId, userId),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['residences', residenceId, 'users'] });
    },
  });
}

export function useJoinResidence() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: (code: string) => residencesApi.joinWithCode({ code }),
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['residences'] });
    },
  });
}
```

### Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Commit

```bash
git add -A && git commit -m "feat: add residence sharing (share code, join, user management) and contractor .honeydue export/import"
```

## Task 3: Profile Settings

**Depends on:** Task 1

**Files:**
- Create: `src/app/app/settings/profile/page.tsx`
- Create: `src/components/settings/profile-form.tsx`
- Create: `src/components/settings/change-password-form.tsx`
- Create: `src/components/settings/delete-account-section.tsx`
- Create: `src/components/settings/theme-picker.tsx`
- Modify: `src/lib/api/auth.ts` (add changePassword and deleteAccount functions if missing)

### API additions needed in auth.ts

Check if these exist, add if missing:
```typescript
export async function changePassword(data: { current_password: string; new_password: string }): Promise<MessageResponse> {
  const res = await fetch('/api/proxy/auth/change-password/', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json', 'X-Timezone': timezone() },
    body: JSON.stringify(data),
  });
  return handleResponse<MessageResponse>(res);
}

export async function deleteAccount(): Promise<MessageResponse> {
  const res = await fetch('/api/proxy/auth/delete-account/', {
    method: 'DELETE',
    headers: { 'Content-Type': 'application/json', 'X-Timezone': timezone() },
  });
  return handleResponse<MessageResponse>(res);
}
```

### Components

**profile-form.tsx** — Edit first name, last name, email:
- Zod schema: first_name (required), last_name (required), email (required, valid email)
- Pre-fills from current user (from auth store)
- On submit: calls `authApi.updateProfile()` → updates auth store user
- Success toast / inline success message

**change-password-form.tsx** — Change password:
- Zod schema: current_password (required, min 8), new_password (required, min 8), confirm_password (must match new_password)
- On submit: calls `authApi.changePassword()` → clear form on success

**delete-account-section.tsx** — Danger zone:
- Red bordered card with warning text
- "Delete Account" button → ConfirmDialog with "Type DELETE to confirm" pattern
- On confirm: calls `authApi.deleteAccount()` → logout → redirect to login

**theme-picker.tsx** — Visual theme selector:
- Grid of 11 theme swatches (colored circles/squares from theme-config)
- Click to select → applies theme via `useTheme()` hook from existing theme store
- Dark/light toggle using existing theme store
- Read theme config from `src/lib/themes/theme-config.ts`

### Profile page

```tsx
// src/app/app/settings/profile/page.tsx
"use client";

// 4 sections stacked vertically:
// 1. ProfileForm (personal info)
// 2. ChangePasswordForm
// 3. ThemePicker
// 4. DeleteAccountSection (danger zone at bottom)
```

### Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Commit

```bash
git add -A && git commit -m "feat: add profile settings — edit info, change password, theme picker, delete account"
```

## Task 4: Notifications + Subscription

**Depends on:** Task 1

**Files:**
- Create: `src/app/app/settings/notifications/page.tsx`
- Create: `src/app/app/settings/subscription/page.tsx`
- Create: `src/components/settings/notification-preferences.tsx`
- Create: `src/components/settings/subscription-status.tsx`
- Create: `src/components/settings/feature-comparison.tsx`
- Create: `src/components/shared/upgrade-prompt.tsx`

### Notification Preferences

**notification-preferences.tsx** — Toggle switches per notification type:
- Uses `useNotificationPreferences()` to load current state
- Each preference row: label, description, toggle switch (shadcn Switch component — install via shadcn if not present)
- On toggle: calls `useUpdatePreferences()` with changed field
- Preference types: Task Reminders, Task Completions, Residence Updates, Share Notifications, Marketing

**Notifications page** (`/app/settings/notifications`):
- NotificationPreferences component
- Section header "Notification Preferences"
- Each toggle saves immediately (optimistic update)

### Subscription

**subscription-status.tsx** — Current plan display:
- Uses `useSubscriptionStatus()` to load tier, limits, usage
- Shows current tier name (Free/Premium)
- Progress bars for usage: residences (X/max), tasks per residence (X/max), contractors (X/max), documents (X/max)
- If free tier: show upgrade CTA section

**feature-comparison.tsx** — Free vs Premium comparison:
- Uses `useFeatureBenefits()` to load feature list
- Two-column comparison table: Free vs Premium
- Check/cross icons per feature
- "Upgrade on App Store" button linking to App Store

**upgrade-prompt.tsx** — Reusable upgrade prompt dialog:
- Shown when user hits a tier limit (e.g., max residences reached)
- Takes `feature` prop (what they're trying to do)
- Shows limit info + upgrade CTA
- Uses shadcn Dialog
- Can be imported by any domain page that needs feature gating

**Subscription page** (`/app/settings/subscription`):
- SubscriptionStatus card at top
- FeatureComparison below
- If premium: show expiry date, management info

### Install Switch component

```bash
npx shadcn@latest add switch
```

### Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Commit

```bash
git add -A && git commit -m "feat: add notification preferences and subscription status with feature comparison"
```

## Task 5: Onboarding Wizard

**Depends on:** Task 1

**Files:**
- Create: `src/app/onboarding/page.tsx`
- Create: `src/app/onboarding/layout.tsx`
- Create: `src/components/onboarding/welcome-step.tsx`
- Create: `src/components/onboarding/choose-path-step.tsx`
- Create: `src/components/onboarding/create-residence-step.tsx`
- Create: `src/components/onboarding/first-task-step.tsx`
- Create: `src/components/onboarding/join-residence-step.tsx`
- Create: `src/components/onboarding/complete-step.tsx`
- Create: `src/stores/onboarding.ts`

### Onboarding Zustand Store

```typescript
// src/stores/onboarding.ts
import { create } from "zustand";

interface OnboardingState {
  currentStep: number;
  path: "create" | "join" | null;
  residenceId: number | null;
  isComplete: boolean;
  nextStep: () => void;
  prevStep: () => void;
  setPath: (path: "create" | "join") => void;
  setResidenceId: (id: number) => void;
  complete: () => void;
  reset: () => void;
}

export const useOnboardingStore = create<OnboardingState>()((set) => ({
  currentStep: 0,
  path: null,
  residenceId: null,
  isComplete: false,
  nextStep: () => set((s) => ({ currentStep: s.currentStep + 1 })),
  prevStep: () => set((s) => ({ currentStep: Math.max(0, s.currentStep - 1) })),
  setPath: (path) => set({ path, currentStep: 2 }),
  setResidenceId: (id) => set({ residenceId: id }),
  complete: () => set({ isComplete: true }),
  reset: () => set({ currentStep: 0, path: null, residenceId: null, isComplete: false }),
}));
```

### Onboarding Layout

- Clean, centered layout (no sidebar or app shell)
- Progress indicator (step dots or progress bar)
- honeyDue logo at top

### Steps

**Step 0: Welcome** — "Welcome to honeyDue!" message, illustration, "Get Started" button

**Step 1: Choose Path** — Two cards: "Create a new residence" (House icon) and "Join an existing residence" (Users icon). Clicking sets path and advances.

**Path A — Create:**
- **Step 2a: Create Residence** — Simplified ResidenceForm (name, address, type only). On submit: creates residence via `useCreateResidence()`, stores ID, advances.
- **Step 3a: First Task (optional)** — "Add your first task?" Quick task form (title + due date only) or "Skip" button. On submit: creates task, advances. On skip: advances.
- **Step 4a: Complete** — "You're all set!" Redirect to `/app/residences/${id}`

**Path B — Join:**
- **Step 2b: Join Residence** — Code input (6-char) or .honeydue file import. On submit: joins via API, advances.
- **Step 3b: Complete** — "Welcome to the residence!" Redirect to residence detail.

### Onboarding trigger

After login/register, check if user has 0 residences → redirect to `/onboarding`.
This is done via middleware or the auth store's login flow.
For now, just mark `localStorage.setItem('onboarding_complete', 'true')` after completion, and check in the app layout.

### Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Commit

```bash
git add -A && git commit -m "feat: add onboarding wizard with create/join paths"
```

## Task 6: Enhanced Dashboard + Task Reports

**Depends on:** Task 1

**Files:**
- Modify: `src/app/app/page.tsx` (enhance existing dashboard)
- Create: `src/components/dashboard/task-completion-chart.tsx`
- Create: `src/components/dashboard/recent-activity.tsx`
- Create: `src/components/dashboard/stats-cards.tsx`
- Modify: `src/app/app/residences/[id]/page.tsx` (add "Download Report" button)

### Enhanced Dashboard

Replace the current simple dashboard with the spec's design:

**stats-cards.tsx** — Top row of stat cards:
- 4 cards: Overdue (red), Due Today (orange), Active (blue), Completed (green)
- Data from `useTasks()` kanban response `total_summary` field
- Each card: count, label, colored icon

**task-completion-chart.tsx** — Area chart using Recharts:
- Uses task completion data (from completions API or derived from kanban data)
- Shows last 30 days of completions as an area chart
- `<ResponsiveContainer>` + `<AreaChart>` + `<Area>` from recharts
- Styled with theme colors via CSS variables
- If no completion data available, show "No completion data yet" empty state

**recent-activity.tsx** — Recent activity feed:
- Uses `useNotifications(5)` to show last 5 notifications as activity items
- Each item: icon, title, time ago (relative)
- "View all" link to settings/notifications
- If no notifications: "No recent activity"

### Dashboard page structure

```tsx
// src/app/app/page.tsx (enhanced)
// 1. Welcome message with user name (from auth store)
// 2. StatsCards (4-column grid)
// 3. TaskCompletionChart (full width card)
// 4. RecentActivity (list)
```

### Task Report PDF

On residence detail page (`src/app/app/residences/[id]/page.tsx`), add a "Download Report" button:
- Calls `residencesApi.generateTasksReport(residenceId)`
- The API generates a PDF and emails it (existing behavior)
- Show success message "Report sent to your email"
- Alternative: if API returns a PDF URL, trigger browser download

### Verify build

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Commit

```bash
git add -A && git commit -m "feat: add enhanced dashboard with charts and task report PDF download"
```

---

## Task 7: Integration + Verification

**Depends on:** Tasks 2-6

### Step 1: Full build verification

```bash
cd /Users/treyt/Desktop/code/HoneyDue/honeyDueAPI-Web && npm run build
```

### Step 2: Route verification

Confirm all new routes compile:
- `/app/settings/profile`
- `/app/settings/notifications`
- `/app/settings/subscription`
- `/app/residences/[id]/share`
- `/app/residences/join`
- `/onboarding`

### Step 3: Cross-feature integration checks

- TopBar notification bell renders and shows unread count
- Settings hub sidebar navigates between profile/notifications/subscription
- Residence detail has Share and Download Report buttons
- Contractor detail has Share button, list has Import button
- Dashboard shows stats, chart, and recent activity
