+## Components Library
+
+### Implemented Components
+- [x] **Button** - With variants (Primary, Secondary, Danger) - *needs Zed-style refactor*
+- [x] **IconButton** - Icon-only button with styles (Subtle, Filled, Danger) - *NEW*

+- [x] **Modal** - Dialog overlay with backdrop
+- [x] **Input** - Text input with placeholder (not fully functional)
+- [x] **StatusIndicator** - Color-coded status dots
+
+### Missing Components (Slint has)

+
+## Summary Statistics
+
+**Overall Progress**: ~50% complete (up from 48%)
+
+### By Category:
+- **Design System**: 60% (colors good, animations missing)
+- **Layout**: 65% (structure done, window controls working)
+- **Pages**: 40% (structure exists, functionality missing)
+- **Components**: 50% (7/14 components, prelude added)
+- **Bridges**: 40% (structure exists, not functional)
+- **i18n**: 30% (framework setup, macro issues)
+- **Platform Features**: 30% (build fixes, window config aligned)
+- **Build System**: 85% (macOS fixed, workflow ready)
+- **Code Patterns**: 30% (prelude added, need traits)
+
+### Priority Items for Next Phase:
+1. **✅ Fix macOS build** - DONE (removed unsupported linker flag)
+2. **Refactor Button with Zed patterns** - Add traits and builder methods
+3. **Add component prelude** - Export common types and traits
+4. **Implement missing components** - Focus on Checkbox, Select first
+5. **Wire up bridges** - Make daemon control functional
+6. **Add animations** - Duration constants and transitions
+7. **Improve documentation** - Add examples and usage docs
+8. **Test build artifacts** - Verify workflow produces working binaries
