- Add desktop-style marquee drag selection on the webapp library: drag
on blank space to select covered tiles, click blank space to deselect
all
- Multi-select: clicking anywhere on a tile toggles it (fixes a
double-fire that cancelled the toggle so only the checkbox worked);
selection persists across tabs and folder navigation
- Gallery item menus show "View image" / "View video" / "View 3D" above
Add to Folder; menu panels size to content so labels no longer wrap
- Mobile/touch: no tile dragging or marquee (finger drags scroll),
checkbox and menu buttons always visible (no hover on touch), and the
Add to Folder submenu expands inline as an accordion instead of
overflowing the screen
- Select-mode gallery modal: folder cards hide the options menu and
ignore right-click (picker is browse-only)
- Perf: bulk selection moved to a module store with per-tile
subscriptions so selection changes re-render only flipped tiles, never
the page; marquee rectangle is positioned imperatively with cached tile
rects and commits only when coverage changes; webapp date groups
virtualized via the shared LazyDateGroup for smooth scrolling on large
libraries
- Bulk selection bar extracted to its own component, fixed to the
viewport bottom and centered within the content area
