Show HN: AutoPiP – Safari extension for automatic PiP on tab switch (v2)

I posted the first version of AutoPiP here in November 2024. Since then I've kept chipping away at it, and v2 is finally ready.

The premise: I wanted truly automatic PiP for multitasking — switch a tab, video keeps playing in a floating window, no clicking required. Safari is the only browser that allows triggering PiP without a user gesture, which is what makes this possible at all.

v2 adds:

- Global on/off toggle in the toolbar (no need to uninstall to pause it)

- Configurable keyboard shortcut (default ⌥P) to manually trigger PiP

- Blacklist / Whitelist mode to control which sites it activates on

Works on YouTube (including PiP on scroll), Netflix, Twitch, Disney+, MAX, Paramount+, Jellyfin and most generic HTML5 players.

Free, GPL-3.0, no telemetry.

Happy to answer questions about the Safari extension API quirks I ran into.
