SponsorBlock, completed: a shield button on every video's player opens a panel to create segments (mark start/end at the playhead, nudge by half-seconds, test the jump locally, pick a category, submit) and to vote on existing segments; the post-skip notice gains a Report button next to Unskip.

Player buttons are now flat SVG icons that match YouTube's own (no more mismatched emoji), and they dock into YouTube's new sectioned control bar, fixing icons missing on some videos. SponsorBlock skips now show a 7-second notice with an Unskip button that jumps back and stops auto-skipping that segment.

4.3.0: opt-in community data - SponsorBlock segment skipping (per-category, with progress-bar markers), DeArrow community titles/thumbnails, and Return YouTube Dislike counts. All off by default, no new permissions. 4.2.0: playback speed suite, audio compressor, A-B loop, screenshots, comment filtering, Twitch tag/rerun blocking, chat highlight/block filters, deleted-message reveal, emote tab-completion, stream uptime, sidebar hover previews.
