Great to hear! :)

Seems like a plan.

Most browser implementations only allow the creation of one PIP window, because of platform limitations (https://w3c.github.io/picture-in-picture/#one-pip-window)... Is that desirable for WebKitGTK too?

I'm wondering that because, if so, the GTK window creation maybe would need to be in the UIProcess? So in this case we'd need to figure out a path for zero-copy (if that is possible)?

Just some early thoughts. I might be totally wrong there.

Yeah. I intend to start experimenting on it soon :)
