I'm very unsure about if this is the right place.
As I'm not sure if I should call it a fix or a request.
Anyway, I have two monitors, and sometimes LFS opens on my secondary monitor in full mode.
The thing is that I get the message that LFS can't go to window mode because its not on the primary monitor.
If its not too much work could you fix it so that SHIFT + F4 works on the secondary monitor too?
No biggie though.
