Is your feature request related to a problem? Please describe.

Not a problem, and I'm still convinced I might be missing this option, but it would be amazing to allow the window to take over the entire screen. (I'm in Windows 11, but obviously supporting this in Mac and Linux would be fantastic.)

Describe the solution you'd like
A fullscreen mode. Either a 'windowed fullscreen' or a true fullscreen, depending on whichever is easiest with the current codebase.

Describe alternatives you've considered
I can't see the ability to resize the window at present, so the only alternative right now is to have a smaller window in the middle of my larger monitor!
