Add picture-in-picture mode (or just allow right-clicking the video?)

[Anonymous3-a]

Is your feature request related to a problem? Please describe.
No problem, but after coming from YouTube, I sure miss Picture-in-Picture.

Describe the solution you'd like
In case you don't know what Picture-in-Picture is, here's a wikipedia article: https://wikipedia.org/wiki/Picture-in-picture

Describe alternatives you've considered
I used Inspect Element, and got a url like http://localhost:port/stream/<a bunch of characters> that I could put into Firefox and right-click, then click "Picture-in-Picture" in the context menu

Additional context
I don't think there's any additional context for this.
