External Playlist for YouTube door grad13

External Playlist for YouTube turns the habit of piling up "watch later" videos as
browser tabs into a single, durable queue that lives outside YouTube.

■ Stash
Click the toolbar button and every YouTube video tab in the current window is
collected into the queue in tab order, de-duplicated, and the collected tabs are
closed — leaving you one tab instead of thirty. Videos already playing inside a
playlist and /playlist pages are left alone.

■ Bookmark Sync
The queue is stored in a bookmark folder named "External Playlist for YouTube",
so your browser's own bookmark sync carries it between your machines and it
survives a reinstall. A local copy is always kept as a fallback, and the two are
merged on load. There is no account, no server, and no sync service of ours —
nothing ever leaves your browser.

■ Playlist
The sidebar shows the queue as cards with thumbnails and titles. Drag to reorder,
remove a row with one click, and let it play hands-free: auto-advance moves to the
next video when one ends, with loop and shuffle available from the header. Loop
stays in sync with YouTube's own right-click "Loop" setting, and hardware media
keys work.

■ About this add-on
This add-on collects no data, makes no network requests of its own, and uses no YouTube account or API. It is a personal project, built first of all for my own daily use — still, if something is broken for you, or almost works but not quite, I'd like to improve it.
