A video's channel name under the thumbnail is now a link — click it in
either list or tile view and the feed narrows to that channel. It
clears the search box on the way, so arriving at a channel shows the
channel rather than whatever you had been searching for.
On a channel page, an icon button to the right of Local queues every
video listed there. The backend already runs two downloads at a time
and parks the rest, so the whole channel goes into the queue at once
and comes down in order. The button is only there when there is
something left to fetch, and a video that fails reports it on its own
row rather than raising a dialog per failure.
Cancelling a queued download now actually cancels it. Before, a video
waiting for a slot ignored the cancel and started anyway once its turn
came — barely reachable with one-at-a-time downloading, unmissable
when a whole channel is queued. A download re-reads its own state
after claiming a slot and stands down if it is no longer wanted.
Subtitles rendered pinned to the left edge and clipped, in half-grey
karaoke text: YouTube's auto-captions carry align:start position:0% on
every cue plus inline <00:00:12.480><c>word</c> timing tags. Both are
now stripped after download, and existing downloads are tidied the first
time they are listed.
Thumbnails show video length. The Atom feed carries no duration, so it
is read from the watch page and cached — but only a trickle. The first
version fetched 24 pages every 12 seconds at six concurrent, roughly two
requests a second sustained, and YouTube answered by challenging the
whole IP: 'Sign in to confirm you are not a bot', which broke streaming
and downloads too. It is now four pages every five minutes, one at a
time, and stops for the session the moment a batch is refused.
A subtitle chosen in the player becomes the stored preference, so the
next video matches without going back to Settings.
The back and download buttons are square icon buttons; the back glyph
was off-centre because px-2 beat the p-0 meant to clear it.
Window chrome: titleBarStyle Overlay (Transparent left the native bar in
place, white in dark mode, with a dead strip beneath it). The app now
paints that strip itself, so it matches the page background.
Player: prev/next through the feed, a full-screen button, a spinner
while a stream resolves, Open on YouTube on downloaded videos too, and
the description collapsed behind a disclosure.
Downloads default to Best, which reaches real 4K — above 1080p YouTube
serves VP9/AV1, verified to play natively in WKWebView here. Audio stays
pinned to AAC because Opus in MP4 would be silent. A Compatible setting
keeps the old 1080p H.264 behaviour. Files are now named
'<ISO date> - <title> [<id>].mp4'.
Watch progress is recorded and drawn under thumbnails like YouTube's,
and reopening a video resumes where it left off.
Tiles clamp every text line to a fixed height so they share a baseline,
and the search field no longer clips its placeholder.
Fixes a Picture-in-Picture leak: WebKit kept a detached video playing
after the player closed, so a second video could play over the first
with no way to stop it. Every exit path now tears the element down.
Adds a seven-step in-app guide to exporting subscriptions from Google
Takeout, with the real URLs opened in the system browser.
Restyles the app onto the supplied design system: slate/sky palette,
9-15px type ladder, outline-first controls, tiered radii, borders for
separation and shadows only for elevation. Light and dark are both
designed, with a System/Light/Dark control and a pre-paint script so
the window does not flash light on a dark machine.
Importing now replaces the subscription list rather than merging, per
request. Because that can delete downloaded files, a confirmation
dialog names exactly what will go first.
Adds an end-to-end integration test that runs the real pipeline against
live YouTube Atom feeds, verifying the merged feed is newest-first
across channels.
