Rather than when adjusting the screen size it keeps everything the same size and just squishes it, have it so that stuff actually shrinks (like hotkeys so they don't go off screen)

change your monitor

Na, I use it mainly when runing dual clients. I have both halfscreened, but it becomes an issue when I can't see galaxy map or half of my gunners hotkeys.

everything that have absolute size value will not change with your window size indeed, thats by design (we don't want a super large map on a 1980x1050 monitor or a super tiny map on a 800x600 one ).

You could always make yourself a custom skin for your needs, the only thing that will eventually be fixed in your issue is not the actual size of the window but their positioning (automatically moved in the screen if they end up completely out).

Guess that'd be a fix, I was just looking forward to running 8 clients all on 1 window
