[Feature Request] Stay on top toggle button

[Samillion]

A button to toggle "Stay on top" off and on next to the "Stats" button on the right, would be a great addition for convenience sake.

Also, thank you for forking and maintaining this project.

In addition to this, I suggest the button will make the video player resize to bottom-right corner of the screen (like Android PIP mode)
