Functionality is limited to replacing YouTube’s native fullscreen with either the browser’s Fullscreen API or a web-based maximization (and its variants).

By default, it uses the browser’s Fullscreen API.
Double-click or Enter toggles maximization; single-click pauses the video.

The web-based maximization is implemented in the crudest possible way—hence no UI.
Anyway, only I will use it.

A personal bias regarding user preferences:

Since I’ve already made the changes,
70% of users will adapt,
29% will find it very inconvenient and insist on changing it back,
and only 1% actually prefer web-based maximization.
But since it’s just a few lines of code, I’ll bundle it in anyway.
