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
