A reusable BackToTop fades in once the active page's <main> is scrolled past ~600px and
smooth-scrolls it back to the top. Rendered once at the App root, portaled to <body> for
viewport-fixed placement (bottom-right, below the chat dock), and re-binds to the live <main> on
navigation (page or channel change) so it works on every scrollable page incl. the channel page.
EN/HU/DE.
The pending-access-requests notification still said "review in Settings -> Account",
but that moved to the new Users page in 5a. Update the text (EN/HU/DE), and give the
notification a durable inbox link ("Review" -> Users page) via a new access-requests
meta kind (persists across reload, unlike a live action callback). Also stop it
piling up: persisted notices reload as dismissed history, so the old dedupe never
matched and a fresh copy was added every load — now removeByMetaKind drops any prior
access-requests notice before re-issuing, keeping exactly one current nudge.
Login page quietly probes /auth/demo (debounced) as a valid email is
typed/pasted and reloads into the app on a match — no visible button.
Demo sessions default to the whole library, get a one-time shared-account
warning, never see the YouTube-connect onboarding/access UI or sync
actions, and admins get a demo whitelist + reset panel in Settings.
Add a sort toolbar to the Playlists page: Title A-Z/Z-A, shortest/longest first,
and a 'group by channel' toggle that groups items by channel (A-Z) and applies the
chosen sort within each group. Applying a sort reorders the items and persists via
the existing reorder API.
The item order is now an undoable value: drag, sort and grouping all go through it,
so every change is reversible via undo/redo buttons and Ctrl/Cmd+Z / Ctrl+Y
(Ctrl+Shift+Z). Built on two reusable pieces, not playlist-specific:
- useUndoable<T> — a generic past/present/future snapshot hook (set/undo/redo/reset
+ canUndo/canRedo), ref-backed so callbacks are stable and never see a stale snapshot;
onApply runs the side effect (here: persist order).
- UndoToolbar — undo/redo buttons + keyboard shortcuts, plain props so any undo
source can use it.
Undo history is reset only when the item set actually changes (different playlist or
add/remove), so a refetch confirming our own reorder doesn't wipe it; membership
changes (remove) clear history since they aren't reorder-undoable. Trilingual.
Add a promise-based ConfirmProvider + useConfirm() hook (built on the Modal shell,
liquid-glass styling, danger variant, Esc/backdrop = cancel, Enter = confirm) so
confirmations match the app instead of the native browser dialog. Wire it in at the
app root and replace both window.confirm call sites (playlist delete, channel
unsubscribe). Trilingual common.confirm/confirmTitle strings.
Login screen (with a language picker), header, account menu, sync status, About and
Release Notes dialogs, and the version banner are now fully translated in Hungarian,
English and German.
