- Add a theme-aware glass surface system (.glass/.glass-card + ambient backdrop,
performance-mode opt-out) and apply it across panels, popovers, toasts, cards,
sidebar widgets, channel rows, video cards and login.
- SettingsPanel: slide in/out animation, glass styling, wrapping pill tabs (no
horizontal scrollbar) with a prominent active state.
- Notifications: auto-dismiss can be switched off (stays until closed); the test
notification now also triggers the alert sound; resume a suspended AudioContext.
- Add an app-wide, toggleable hint/tooltip system (lib/hints + Tooltip) and wire
hints across the settings and channel-manager surfaces; persisted per account.
- NotificationCenter closes on outside click (document listener, not an overlay
that the blurred header trapped) and no longer needs a second bell click.
- Toasts show a level-colored countdown bar and auto-dismiss faster (6s default).
- Hidden-video notifications carry structured meta so the center offers an in-app
'Find in feed' (jump to that channel's hidden videos) and a one-click 'Unhide',
working even after a reload when the live Undo callback is gone.
- Hidden view shows an Unhide action (eye icon) instead of Hide
- Upload-date filter: From/To date range (inclusive); feed shows only videos
published in that window (backend published_after / published_before)
- New sort options: Name (A-Z) and Channel subscribers, alongside date/views/
duration/shuffle
- Native controls follow the theme via color-scheme (dark date picker)
- Vite + React + TS + Tailwind SPA served by FastAPI (multi-stage Docker build)
- Four color schemes (Midnight default, Forest, Slate, YouTube) x dark/light,
adjustable text size; persisted to user preferences and localStorage
- Header search, grid/list toggle, theme menu; sidebar filters (show state,
sort, include Shorts/live, language + topic tag chips with any/all matching)
- Infinite-scroll feed of video cards; click opens youtube.com in a new tab;
per-video watched / saved / hidden actions with optimistic updates
- SPA fallback routing; login screen for unauthenticated users
