Is your feature request related to a problem? Please describe.
My feature request is related to a problem (kind of). I'm always annoyed when I'm watching a playlist and the next video comes on and I manually have to fullscreen it.

Describe the solution you'd like
I think the solution would be to start the next video from the playlist in fullscreen if the video that was playing before fullscreen.

Describe alternatives you've considered
An alternative solution would be a toggle in the bottom of the screen that allows the user to choose if they want to start the next video in fullscreen.
