## Known Issues

### Active Issues (Non-Critical)

1. **UI-001: Emoji Replacement Incomplete**
   - Some plugins still use emojis as fallback
   - SVG icons created but not all integrated
   - **Priority:** Low
   - **Workaround:** Emojis render on most modern systems

2. **UI-002: Activity Bar Auto-Hide Delay**
   - QTimer-based implementation needs refinement
   - **Priority:** Low
   - **Impact:** Minor UX inconsistency

3. **API-001: Widget Preset Validation**
   - create_from_preset may return None
   - **Priority:** Medium
   - **Workaround:** Check return value

4. **DOC-001: Some Test Modules Incomplete**
   - widget_tests.py, settings_tests.py templates only
   - **Priority:** Low
   - **Impact:** Testing framework ready for expansion

### Resolved Issues
All critical and high-priority issues have been resolved. See "Bugs Fixed" section.

## Conflict Analysis

**Result: NO CONFLICTS DETECTED**

### Coordination Success Factors:

1. **Clear Ownership Boundaries**
   - Each agent owned distinct file sets
   - No overlapping modifications

2. **Communication via Documentation**
   - Agents updated shared docs
   - Status reports tracked progress

3. **Coordinator Oversight**
   - 5-minute status checks
   - Early conflict detection
   - Resource arbitration

4. **Modular Architecture**
   - Plugin-based system enables isolation
   - Core changes minimized
   - Clear interfaces between components

---

## Recommendations for Future Work

### Immediate (Next Sprint)
1. Complete emoji → SVG replacement in all plugins
2. Implement remaining test modules
3. Add performance benchmarks to CI/CD

### Short Term (1-2 weeks)
1. Create GitHub Actions workflow
2. Add code coverage reporting
3. Implement visual regression tests
4. Expand Home Assistant integration

### Long Term (1-2 months)
1. Plugin marketplace implementation
2. Cloud sync for settings
3. Mobile companion app
4. Advanced analytics dashboard
