## Statistics

### Flag Coverage

- **Modules with Settings Flags:** 20 (40%)
- **Modules with User Flags:** 20 (40%)
- **Modules Missing Flags:** 30 (60%)

### Categories Needing Attention

1. **CRM Features** - 3 of 4 modules missing flags
2. **Advanced Features** - 8 of 8 modules missing flags
3. **Tools & Data** - 3 of 3 modules missing individual flags
4. **Admin Features** - 8 of 8 modules missing flags (may be intentional)

### Priority for Flag Addition

**High Priority:**
- `invoices` (core finance feature)
- `expenses` (core finance feature)
- `contacts`, `deals`, `leads` (CRM features)
- `workflows`, `time_approvals` (workflow features)

**Medium Priority:**
- `time_entry_templates`
- `integrations`, `import_export`, `saved_filters` (individual flags)
- `team_chat`, `activity_feed` (collaboration features)

**Low Priority:**
- Admin features (may remain admin-only)
- `client_portal_customization` (admin feature)

---

## Recommendations

1. **Immediate Actions:**
   - Add flags for high-priority modules
   - Create module registry system
   - Add route protection for critical modules

2. **Short-term (1-2 weeks):**
   - Complete flag coverage for all modules
   - Implement module registry
   - Refactor navigation

3. **Medium-term (1 month):**
   - Admin UI for module management
   - Dependency validation
   - Comprehensive testing

4. **Long-term (Future):**
   - Module plugin system
   - Module marketplace
   - Advanced permission system

---

## Next Steps

1. ✅ Review module inventory
2. ✅ Identify missing flags
3. ⏳ Create module registry
4. ⏳ Add missing flags
5. ⏳ Implement route protection
6. ⏳ Refactor navigation
7. ⏳ Create admin UI
