v0.3.13
Playback was quieter than YouTube Music (#6). Two causes: the loudness normalisation targeted -14 LUFS like the video site instead of YTM's -7, which cost about 6 dB on a typical modern master and pulled down most tracks YTM leaves alone; and because mpv's audio filter is global rather than per-track, every song after the first in a gapless run played at the first one's attenuation for the rest of the session. Both fixed, so volumes now match YouTube Music at the same slider position.
The volume level is remembered across restarts, and a volume drag no longer stutters: it commits once per frame instead of every 100ms, which is what made fast drags pop.
Dragging the slider past either end used to open or close the now-playing view, since releasing outside the slider lands the click on the bar. Fixed. Clicking the now-playing artwork now toggles playback, and flashes the play or pause icon over it.
Settings > About has a new switch for the launch update check. It's on by default, and turning it off skips the check entirely (no request, no banner), leaving "Check for updates" as the way to look.
