"select the game" fills half the screen with white "elements"
When launching the editor, I was greated by the Global Preferences
dialog, and when clicking on Select the game
droplist, this is (part of) what I see:
Here, what should probably be done is to limit the number of displayed elements to a reasonable number (say, 7, as this is kind of a magic number of GUI designing) and have a scrollbar: this would scale much better. Actually, it might be a wiser choice to just use a list, instead of a droplist: this would allow further improvements in future, like having user filters remembered (I doubt many users do maps for all those games, right?) and it would scale much more naturally.
