Fullscreen option in settings.

Please add an option for automatically starting the app in fullscreen. The flatpak version won't let me fullscreen the program on steam deck because I can't add --start-fullscreen to the thing and none of the other fixes seem to work.

You should be able to toggle fullscreen mode at any time with the standard F11 key. It should be on the steam deck keyboard.

The keyboard on the Steam Deck does not have the F Keys at all. If you need them, you have to bind f11 to one of the buttons on the Deck and it would have a black bar despite supposedly being fullscreened (not sure why). I just opened it again today and there is no black bar. I have no clue what changed but I guess maybe rebooting after having saved and set the fullscreen option in desktop mode fixed it?
I still think a fullscreen toggle built into the menu (preferably with a resolution picker) is a good idea to have, just in case the fullscreen stops working for some reason or if people to run it through steam or some other launcher program.
Sorry for opening this issue if it seems like too much work for a niche solution to a problem most people probably won't have.
