- Fix 'Show in finder' for unfinished entries to open destination folder
- Add 'Add to queue' submenu for unfinished items
- Support Shift/Cmd modifiers for multi-selection in download list
- Implement mass-action context menu for multi-selected downloads
- Enhance DeleteConfirmationModal to handle mass deletions gracefully
