@sgunhouse Thanks!

Why is it so hard to find documentation for this? I mean, you can find it if you know what to look for. Otherwise, you're S.O.L.

When I play a YouTube video and I hover the pointer over the video, a couple of widgets show up at the top. One is for playing picture-in-picture. I have no idea what the other widget does; there is no tooltip to let me know. And clicking on it doesn't seem to do anything.
