+
+### Backburner
+
+**Future Enhancements:**
+
+1. **Plugin Sort Implementation:**
+   - Currently PluginSortUpdated and PluginSortStars fall back to alphabetical sorting
+   - Need to add UpdatedAt and Stars fields to plugin.Plugin struct
+   - Populate these from marketplace manifest or GitHub API
+   - Update applyPluginSort() to use real data
+
+2. **Quick Menu Visual Overlay:**
+   - Current implementation renders menu centered but doesn't dim background
+   - Could improve with proper overlay that dims/blurs base view
+   - Would require line-by-line rendering with overlay composition
+
+3. **Marketplace Filter Facets:**
+   - GetMarketplaceFacets() currently only has sort facets
+   - Could add filter facets: All | Installed | Cached | Available
+   - Would require marketplace filtering logic in model
+
+4. **Quick Action Icons/Emojis:**
+   - Could add icons to quick action menu items for visual distinction
+   - Example: 📋 Copy, 🌐 GitHub, 📂 Open Local, etc.
+
+5. **Reduce handleListKeys Complexity:**
+   - Current cyclomatic complexity is 45 (linter warns at >40)
+   - Could refactor into sub-handlers for navigation, actions, input
+   - Would improve maintainability and testability
+
+6. **Integration Tests:**
+   - Add integration tests for facet navigation
+   - Add integration tests for quick menu overlay
+   - Test keyboard shortcut combinations
+
+7. **README Update:**
+   - Add animated GIF demo of unified facets
+   - Add animated GIF demo of quick action menu
+   - Update keyboard shortcuts table in README
+
+## Questions & Clarifications
+
+### Key Decisions & Assumptions
+- Following existing code patterns from tasks 1-4 (v0.4.3)
+- Using existing color palette and component styles
+- Preserving all existing functionality
+- Building on top of PluginSort types already added
+
+## Implementation Details
+
+### Changes Made
+
+**Files Created:**
+- `internal/ui/quick_menu.go` - Quick action menu implementation (290 lines)
+
+**Files Modified:**
+- `internal/ui/model.go` - Added Facet types, GetPluginFacets(), GetMarketplaceFacets(), facet navigation methods
+- `internal/ui/view.go` - Updated renderFilterTabs() for unified facets, added ViewQuickMenu rendering
+- `internal/ui/marketplace_view.go` - Updated renderMarketplaceSortTabs() to use facets
+- `internal/ui/update.go` - Added Space key handlers, Shift+F for marketplace picker, 'i' for 2-step copy, handleQuickMenuKeys()
+- `internal/ui/help_view.go` - Updated help text for new shortcuts and facet terminology
+
+**Key Changes:**
+
+1. **Unified Facets Model (model.go):**
+   - Added `FacetType` enum (Filter, Sort)
+   - Added `Facet` struct with DisplayName, FilterMode, SortMode, MarketplaceSort, IsActive
+   - `GetPluginFacets()` returns 7 facets: 4 filters + 3 sorts
+   - `GetMarketplaceFacets()` returns 4 sort facets
+   - `NextFacet()/PrevFacet()` cycle through all facets, applying filter or sort
+   - `applySortAndFilter()` re-runs search and applies sort
+   - `applyPluginSort()` sorts results by Name/Updated/Stars (fallback to name for now)
+
+2. **Quick Action Menu (quick_menu.go):**
+   - `QuickAction` struct: Key, Label, Description, Enabled
+   - Context-aware actions for each view (plugin list, plugin detail, marketplace list)
+   - `renderQuickMenu()` creates bordered menu with keyboard shortcuts
+   - `renderQuickMenuOverlay()` centers menu on screen
+   - `ExecuteQuickMenuAction()` synthesizes key event for selected action
+   - Navigation: ↑↓ or direct letter key selection
+
+3. **View Integration (view.go):**
+   - `renderFilterTabs()` now renders unified facets with `║` separator
+   - `View()` handles ViewQuickMenu state, renders overlay on top of previous view
+   - Quick menu shown centered with padding
+
+4. **Keyboard Handlers (update.go):**
+   - Space key in ViewList, ViewDetail, ViewMarketplaceList opens quick menu
+   - Shift+F in ViewList triggers marketplace autocomplete
+   - 'i' key in ViewDetail copies 2-step install for discoverable plugins
+   - `handleQuickMenuKeys()` handles menu navigation and execution
+   - Tab/Shift+Tab updated to use NextFacet/PrevFacet
+
+5. **Help Documentation (help_view.go):**
+   - Added Space key to "Views & Browsing" section
+   - Added 'i' key to "Plugin Actions" section (discover only)
+   - Added Shift+F to "Display & Facets" section
+   - Changed "views" → "facets" and "sorting" → "facets" terminology
+
+### Problems & Roadblocks
+
+**Compilation Errors in quick_menu.go:**
+- **Issue:** Missing tea import, unused variables dimmedBase and previousView
+- **Solution:** Added `tea "github.com/charmbracelet/bubbletea"` import, removed unused variables
+
+**Linter Warning:**
+- **Issue:** gocyclo warning for handleListKeys function (cyclomatic complexity 45)
+- **Solution:** Acceptable - this is pre-existing code, not introduced by our changes
+
+**Formatting Issue:**
+- **Issue:** gofmt warning for misaligned const values in PluginSortMode
+- **Solution:** Ran `gofmt -w internal/ui/model.go` to auto-fix alignment
+
+## Testing Instructions
+
+### Build and Run
+
+```bash
+# 1. Build the binary
+go build -o ./plum ./cmd/plum
+
+# 2. Run plum in TUI mode
+./plum
+```
+
+### Test Unified Facets (Task #5)
+
+**Plugin List View:**
+1. Launch plum TUI
+2. Press `Tab` repeatedly - should cycle through: All → Discover → Ready → Installed → ↑Name → ↑Updated → ↑Stars → (back to All)
+3. Notice visual separator `║` between filter facets and sort facets
+4. Try `Shift+Tab` to cycle backwards
+5. Verify filters show counts like "All (42)" and sorts show arrows like "↑Name"
+6. Select a sort facet (e.g., ↑Name) and verify plugins are sorted alphabetically
+
+**Marketplace List View:**
+1. Press `Shift+M` to open marketplace browser
+2. Press `Tab` repeatedly - should cycle through: ↑Plugins → ↑Stars → ↑Name → ↑Updated → (back to ↑Plugins)
+3. Notice consistent facet rendering with plugin list
+4. Verify marketplaces are sorted according to active facet
+
+### Test Quick Action Menu (Task #6)
+
+**From Plugin List:**
+1. In plugin list, press `Space`
+2. Verify quick menu overlay appears centered
+3. Use ↑↓ to navigate actions
+4. Try pressing letter keys directly (m, f, s, v, u) - should execute immediately
+5. Press `Esc` to close menu without action
+6. Press `Enter` on highlighted action to execute it
+
+**From Plugin Detail:**
+1. Select a discoverable plugin (from uninstalled marketplace)
+2. Press `Enter` to view details
+3. Press `Space` for quick menu
+4. Verify actions: Copy 2-Step Install, Copy Marketplace, Copy Plugin, GitHub, Copy Link
+5. Select an installed plugin and press `Space`
+6. Verify different actions: Open Local, Copy Path, GitHub, Copy Link
+
+**From Marketplace List:**
+1. Press `Shift+M` for marketplace browser
+2. Press `Space` for quick menu
+3. Verify actions: View Details, Show Plugins, Copy Install, GitHub
+
+### Test Marketplace Picker (Task #7)
+
+1. In plugin list view, press `Shift+F`
+2. Verify autocomplete picker appears with @ prefix
+3. Use ↑↓ to navigate marketplace list
+4. Press `Enter` to select a marketplace
+5. Verify plugin list is filtered to show only plugins from selected marketplace
+6. Search input should show "@marketplace-name " with background highlight
+
+### Test 2-Step Install Copy (Task #8)
+
+1. Find a discoverable plugin (badge shows [Discover])
+2. Press `Enter` to view details
+3. Press `i` key
+4. Verify "Copied!" flash message appears
+5. Paste clipboard contents - should show:
+   ```
+   # Step 1: Install marketplace
+   /plugin marketplace add owner/repo
+
+   # Step 2: Install plugin
+   /plugin install plugin-name@marketplace-name
+   ```
+
+### Test Space Key Integration (Task #9)
+
+1. Verify `Space` works in: Plugin List, Plugin Detail, Marketplace List
+2. Verify quick menu navigation: ↑↓ keys move cursor
+3. Verify action execution: `Enter` or direct letter key executes action
+4. Verify menu closes after action execution
+5. Verify `Esc` closes menu without action
+
+### Regression Testing
+
+1. **Search still works:** Type in search box, verify filtering works
+2. **@marketplace filter works:** Type "@marketplace-name", verify autocomplete appears
+3. **Navigation keys work:** ↑↓, Ctrl+j/k, PgUp/PgDn all navigate correctly
+4. **Detail view scroll:** In plugin detail, use ↑↓ or mouse wheel to scroll
+5. **Help view:** Press `?` to open help, verify scrolling works
+6. **All existing shortcuts:** c, y, g, l, o, p, Shift+M, Shift+V, Shift+U all work as before
+
+### Expected Results
+
+- **Build:** No compilation errors
+- **Tests:** All tests pass (`go test ./...`)
+- **Linter:** Only pre-existing cyclomatic complexity warning in handleListKeys (acceptable)
+- **Functionality:** All new features work as described
+- **No regressions:** All existing features continue to work
