## Summary
- Implement pagination for media assets history to handle large datasets
efficiently
- Add infinite scroll support with approach-end event handler
- Support offset parameter in history API for both V1 and V2 endpoints
## Changes
- Add offset parameter support to `api.getHistory()` method
- Update history fetchers (V1/V2) to include offset in API requests
- Implement `loadMoreHistory()` in assetsStore with pagination state
management
- Add `loadMore`, `hasMore`, and `isLoadingMore` to IAssetsProvider
interface
- Add approach-end handler in AssetsSidebarTab for infinite scroll
- Set BATCH_SIZE to 200 for efficient loading
## Implementation Improvements
Simplified offset-based pagination by removing unnecessary
reconciliation logic:
- Remove `reconcileHistory`, `taskItemsMap`, `lastKnownQueueIndex`
(offset is sufficient)
- Replace `assetItemsByPromptId` Map → `loadedIds` Set (store IDs only)
- Replace `findInsertionIndex` binary search → push + sort (faster for
batch operations)
- Replace `loadingPromise` → `isLoadingMore` boolean (simpler state
management)
- Fix memory leak by cleaning up Set together with array slice
## Test Plan
- [x] TypeScript compilation passes
- [x] ESLint and Prettier formatting applied
- [x] Test infinite scroll in media assets tab
- [x] Verify network requests include correct offset parameter
- [x] Confirm no duplicate items when loading more

## Summary
- Reorganized media asset card layout for improved UX
- Moved duration/format chips to top-left (visible in default state)
- Replaced multiple action buttons with zoom + more menu pattern
- Repositioned output count to top-right for better visibility
## Changes
1. **Duration & format chips**: Moved from bottom-left to top-left,
shown when card is not hovered and media is not playing
2. **Media actions**: Simplified to zoom button + more menu (contains
delete, download options), shown on hover or during playback
3. **Output count**: Relocated from bottom-right to top-right for
consistent positioning
## Test plan
- [x] Verify duration/format chips appear in top-left when card is idle
- [x] Confirm action buttons (zoom + more) appear on hover
- [x] Check output count displays correctly in top-right
- [x] Test transitions between hover/non-hover states
- [x] Verify media playback doesn't interfere with UI elements

## Summary
Implements file explorer-style multi-selection functionality for media
assets in the AssetsSidebarTab component.
## Changes
### Multi-Selection Interactions
- **Normal click**: Single selection (clears previous, selects new)
- **Shift + click**: Range selection (from last selected to current)
- **Ctrl/Cmd + click**: Toggle individual selection
### State Management
- Added `assetSelectionStore` to manage selected asset IDs using Set
- Created `useAssetSelection` composable for selection logic and
keyboard state
### UI Enhancements
- Display selection count in footer (output tab only)
- Interactive selection count that shows "Deselect all" on hover
- Added bulk action buttons for download/delete (UI only)
### Translation Keys
Added new keys under `mediaAsset.selection`:
- `selectedCount`: "{count} selected"
- `deselectAll`: "Deselect all"
- `downloadSelected`: "Download"
- `deleteSelected`: "Delete"
## Test Plan
- [x] Open Assets sidebar tab
- [x] Switch to Generated tab
- [x] Test single selection with normal click
- [x] Test range selection with Shift + click
- [x] Test toggle selection with Ctrl/Cmd + click
- [x] Verify selection count updates correctly
- [x] Test hover interaction on selection count
- [x] Click "Deselect all" to clear selection
- [x] Test bulk action buttons (UI only)
## Notes
- Bulk download/delete functionality to be implemented in separate PR
- Selection UI currently only shows in output (Generated) tab

## 📋 Overview
Implemented a new Media Assets sidebar tab in ComfyUI for managing
user-uploaded input files and generated output files. This feature
supports both local and cloud environments and is currently enabled only
in development mode.
## 🎯 Key Features
### 1. Media Assets Sidebar Tab
- **Imported** / **Generated** files separated by tabs
- Visual display with file preview cards
- Gallery view support (navigable with arrow keys)
### 2. Environment-Specific Implementation
- **`useInternalMediaAssets`**: For local environment
- Fetches file list via `/files` API
- Retrieves generation task execution time via `/history` API
- Processes history data using the same logic as QueueSidebarTab
- **`useCloudMediaAssets`**: For cloud environment
- File retrieval through assetService
- History data processing using TaskItemImpl
- Auto-truncation of long filenames over 20 characters (e.g.,
`very_long_filename_here.png` → `very_long_...here.png`)
### 3. Execution Time Display
- Shows task execution time on generated image cards (e.g., "2.3s")
- Calculated from History API's `execution_start` and
`execution_success` messages
- Displayed at MediaAssetCard's duration chip location
### 4. Gallery Feature
- Full-screen gallery mode on image click
- Navigate between images with keyboard arrows
- Exit gallery with ESC key
- Reuses ResultGallery component from QueueSidebarTab
### 5. Development Mode Only
- Excluded from production builds using `import.meta.env.DEV` condition
- Feature in development, scheduled for official release after
stabilization
