 - **Sponsored ranges:** optional [SponsorBlock](https://sponsor.ajay.app/) sponsor/skip ranges paint the existing track crimson without adding chapter boundaries or changing chapter gaps. Hover shows **Sponsor** alongside any chapter title, centered over the sponsored range itself even when it crosses chapter boundaries; accessibility also identifies sponsored ranges. Inside a range, **Skip Sponsor** uses the opening/ending button without a timeout or countdown fill. Clicking seeks to the range's end; automatic skipping is a separate opt-in.
 - **Miruro metadata:** titles and opening/ending intervals load independently of playback when available. Small rounded gaps mark interval boundaries in the slider. Inside a segment, **Skip Opening** or **Skip Ending** appears at the top-right below the titlebar for up to ten seconds or until the segment ends; clicking seeks to its end. A light background fill grows as the offer expires, with a short entrance/exit transition; Reduce Motion uses stepped countdown updates without the transition. Ignored offers stay dismissed until the media is closed or replaced. Missing/invalid metadata leaves playback usable, and timings may differ between cuts. Automatic skipping is configurable below.
 - **Resume:** videos resume their saved position; finished videos restart from the beginning. Live and audio-only media do not save progress.
-- **Compact mode:** press **P** for a floating player; double-click it to restore. Drag noninteractive areas to move the window. The queue starts hidden each time you enter compact mode; **⇧⌘L** or **gear → Show Queue** expands it below the video.

+- **Compact mode:** press **P** for a floating player; double-click it to restore. It follows you across desktops and other apps' native fullscreen Spaces while keeping Terebi in the Dock and **⌘Tab**. Moving between compact and normal mode preserves the running player and restores the original window. Drag noninteractive areas to move the window. The queue starts hidden each time you enter compact mode; **⇧⌘L** or **gear → Show Queue** expands it below the video. Its top fade has a 12-point solid section and a 20-point transition, with the first row starting below both. The same shortcut toggles the normal sidebar, whose visibility is preserved when leaving compact mode. Use the titlebar pin to keep the normal window on top.
 - **Quality:** yt-dlp defaults to SDR up to 1080p when resolution is reported. Missing resolution/codec hints are left to native probing. Use **gear → Quality** for other reported resolutions or automatic quality.
