The list is only redrawn when its contents actually changed (compared by a signature of the items), at most once per second — a playing page no longer causes any redraw at all.
While a quality picker is open, refreshes are suppressed entirely, so it can't disappear while you're choosing.

First public release.

• Detects video, audio, HLS (m3u8) and DASH (mpd) streams on the pages you visit
• Quality picker; streams are saved as clean, seekable MP4 files
• Separate audio tracks are merged automatically, so streams keep their sound
• Audio-only extraction to M4A
• Parallel downloading with progress, speed, pause, cancel and a queue
• No size limit: large streams are converted in parts
• Filenames from the page title, optional subfolder, "always ask where to save"
• Free and unlimited, with no data collection
