## Summary

### ✅ FEATURE PARITY ACHIEVED!

All critical features from the legacy UI have been successfully implemented in the NiceGUI version:

**Completed Features:**
1. ✅ AI Stats display with success/failure rates
2. ✅ Advanced sync options (after_id, specific_id, local_only)
3. ✅ Re-analyze Local Archive button
4. ✅ Email search/filter functionality
5. ✅ Page jump input for pagination
6. ✅ Download .eml button in email detail
7. ✅ Provider secrets JSON input (Gmail/M365 credentials)
8. ✅ Auto-scroll logs to bottom

**Low Priority (Optional):**

### Better in NiceGUI
- ✅ Toast notifications instead of alert()
- ✅ Real-time updates via WebSocket (no polling)
- ✅ Better error handling
- ✅ 35% less code (954 lines vs 1460 lines)
- ✅ Type safety with Python
- ✅ Built-in reactive data binding
