Two fixes that surfaced from daily use after the v0.2.2 popout polish round 1.
1. Show download progress on the active thumbnail when the
embedded preview is hidden (gui/app.py)
After the previous fix to suppress the dl_progress widget when
the popout is open, the user lost all visible feedback about
the active download in the main app. The grid had no indicator,
the dl_progress widget was hidden, and the only signal was the
status bar text "Loading #X..." at the bottom edge.
`_on_post_activated` now decides per call whether to use the
dl_progress widget at the bottom of the right splitter or fall
back to drawing the download progress on the active thumbnail
in the main grid via the existing prefetch-progress paint path.
The decision is captured at function entry as
`preview_hidden = not (self._preview.isVisible() and
self._preview.width() > 0)` and closed over by the `_progress`
callback and the `_load` coroutine, so the indicator that
starts on a download stays on the same target even if the user
opens or closes the popout mid-download.
The thumbnail bar uses the same paint path as prefetch
indicators (`set_prefetch_progress(0.0..1.0)` for fill,
`set_prefetch_progress(-1)` for clear), so the visual is
identical and no new widget code was added. `_load`'s finally
block emits the clear when `preview_hidden` was true at start.
Generalizes to any reason the preview is hidden, not just the
popout-open case: a user who has dragged the main splitter to
collapse the preview also gets the thumbnail indicator now,
even with the popout closed.
2. Stop auto-showing the popout overlay on every navigation
(gui/preview.py)
`FullscreenPreview.set_media` ended with an unconditional
`self._show_overlay()` call, which meant the floating toolbar
and video controls bar popped back into view on every left/
right/hjkl navigation between posts. Visually noisy and not
what the user wants once they've started navigating — the
overlay is supposed to be a hover-triggered surface, not a
per-post popup.
Removed the call. The overlay is still shown by:
- `__init__` default state (`_ui_visible = True`), so the
user sees it for ~2 seconds on first popout open and the
auto-hide timer hides it after that
- `eventFilter` mouse-move-into-top/bottom-edge zone (the
intended hover trigger, unchanged)
- Volume scroll on video stack (unchanged)
- Ctrl+H toggle (unchanged)
After this, the only way the overlay appears mid-session is
hover or Ctrl+H. Navigation through posts no longer flashes it
back into view.
