I see. On Mac's WM it's totally different in that applications normally 
stay just the way as they are in windowed mode just the window fills the 
whole screen (or half of the screen) without showing the menu bar, title 
bar and dock. I know of no other application that behaves differently in 
fullscreen mode. (There are a couple of apps that have modes in addition 
to the usual fullscreen mode such as presentation mode for Powerpoint or 
Read Mode in Adobe Reader.)

I think LyX is already catching that signal. For example, because when I 
use the Mac WM's fullscreen button, LyX puts a checkmark on the 
Fullscreen menu.

However, since on Mac the expectation is that one can just work as usual 
with apps in fullscreen/spitscreen, I'd suggest that, if no separation 
between fullscreen and "focus" mode is implemented, to deactivate the 
hiding of Ui elements in fullscreen mode by default. Now that I know 
that I can just deactivate this, I can again work properly in 
fullscreen/splitscreen. But it took me a little too long to realize this.
