I think it would be nice if Orions picture in picture had extra controls such as forward/backward 10 or 15 seconds, and maybe even include a simple playhead skimmer to choose where in the current video you would like to move to.
Having these controls would prevent one from needing to constantly return to the tab in which youre watching the video, interrupting what you're doing.
Apps and extensions which currently do this very well would be Arc Browsers built in Picture in Picture and a Safari extension called Vidimote.
It would help those of us who watch a ton of videos on the side while working, gaming from having to constantly go back to the tab to say go back in the video or to skip forward.
