- Preview/popout toolbar: icon buttons (☆/★, ↓/✕, ⊘, ⊗, ⧉) with QSS object names (#_tb_bookmark, #_tb_save, etc.) for theme targeting - Video controls: QPainter-drawn icons for play/pause, volume/mute; text labels for loop/once/next and autoplay - Popout anchor setting: resize pivot (center/tl/tr/bl/br) controls which corner stays fixed on aspect change, works on all platforms - Hyprland monitor reserved areas: reads waybar exclusive zones from hyprctl monitors -j for correct edge positioning - Layout flip setting: swap grid and preview sides - Compact top bar: AdjustToContents combos, tighter spacing, named containers (#_top_bar, #_nav_bar) for QSS targeting - Reduced main window minimum size from 900x600 to 740x400 - Trimmed bundled QSS: removed 12 unused widget selectors, added popout overlay font-weight/size, regenerated all 12 theme files - Updated themes/README.md with icon button reference

|
URL playback is the fast path for uncached videos: rather than
|
|
waiting for `download_image` to finish writing the entire file
|
|
to disk before mpv touches it, the load flow hands mpv the
|
|
remote URL and lets mpv stream + buffer + render the first
|
|
frame in parallel with the cache-populating download. mpv's
|
|
first frame typically lands in 1-2s instead of waiting for
|
|
the full multi-MB transfer.
|
|
|
|
For URL paths we set the `referrer` per-file option from the
|
|
booru's hostname so CDNs that gate downloads on Referer don't
|
|
reject mpv's request — same logic our own httpx client uses
|
|
in `cache._referer_for`. python-mpv's `loadfile()` accepts
|
|
per-file `**options` kwargs that become `--key=value` overrides
|
|
for the duration of that file.
