Notable Implementation Details

1. Automatic Missing Date Fill: Creates placeholder entries for days without ratings
2. Entry Types: header, listView, filledInMissing - tracks how entries were created
3. Day Filtering: Users can filter which weekdays appear in visualizations
4. CSV Export: Full data portability with all metadata preserved
