## 💡 Tips for Completion

1. **Start with Excel export** - Quick win, users will immediately see value
2. **Invoice duplication** - Another quick win, 15 minutes of work
3. **User settings page** - Unlock all the preference features
4. **Activity feed integration** - Add `Activity.log()` calls gradually as you work on other features
5. **Time entry templates** - Very useful feature, worth the 3-hour investment

---

## 🐛 Known Issues / Future Enhancements

- Email sending requires SMTP configuration (consider adding queuing for production)
- Activity feed might need pagination for high-activity users
- Excel exports don't include charts (could add with openpyxl chart features)
- Bulk operations don't have undo (consider adding soft delete)
- Theme switcher doesn't animate transition (could add CSS transitions)

---

**Total Implementation Time Remaining:** ~12-15 hours for complete implementation
**Quick Wins Available:** Excel export, invoice duplication, settings page (~2 hours)
