Does desktop have good PIP? It obviously matters much less when you have multiple monitor, but I'd love to see OS level PIP support on desktop. Aka, have a video "always on top" in the corner that I can move around and resize while browsing the web, all on the same monitor. Some programs have "always on top" support but there's nothing OS level.
Like someone else below mentioned, MacOS has built in native PIP support for videos at the OS level. Browser-wise it only works in Safari though.
It's also a little hidden in YouTube's site because YouTube hijacks the first right-click. Try this if you have MacOS and want to see how it works with YouTube:
1. Open Safari
2. Go on YouTube
3. Go to any video
5. Right-click then right-click again immediately
6. Select "Enter picture in picture"
It should be available in the right-click menu in the native MacOS video player that most apps build on top of (unless said services hijack the right-click like YouTube). Works well with Netflix, Vimeo, VLC, you name it.
