In a perfect world, individual queue items get a prune button

1. What was the intention behind combining all bulk action buttons into a single dropdown? In my opinion, this results in poor UX.
2. How do we resume individual download? I’d suggest making the Pause button a toggle (Pause/Resume).

3. In the updated version, the “Backend disconnected” message feels more prominent and somewhat out of place compared to the previous layout.

Most invoke bulk actions are in a dropdown.

It is a toggle. Also the pausing feature doesn't work for me so if that portion of the UI is broken you'll need to let me know how to fix it.

3. In the updated version, the “Backend disconnected” message feels more prominent and somewhat out of place compared to the previous layout.

Prominent is good.

Also, if my opinion matters, i'm voting on separate bulk buttons and changing backend status message.

I don't think the backend status needs to even be here, it's already shown in the sidebar and there's nothing special about the queue that would warrant it getting a special badge for it and not the models page, generation page, etc.

“Backend disconnected” was added to address a specific UX gap:

1. When the backend is stopped/crashes (for example via Ctrl+C), installs are paused server-side.
2. During that disconnect window, the frontend can still show stale “In Progress” states.
3. The banner makes it explicit that the data source is currently unavailable and queue status may be outdated.
4. Once the backend reconnects and resync runs, statuses are refreshed.

So this prevents a false impression that downloads are still progressing normally.

Sure, we have a tiny triangle in the sidebar signaling the same thing, but it’s barely noticeable.
