   - Event sourcing replay not fully implemented
   - Rate limiting needs fine-tuning

2. **Frontend**:
   - Some components need accessibility improvements
   - Performance optimization needed for large datasets
   - Offline support not yet implemented

3. **Desktop**:
   - Auto-update needs testing across platforms
   - Deep linking not fully configured
