I'm thinking a landscape layout would solve the issue without further compressing the launcher's contents. I doubt that anyone plays FS on a portrait resolution - and then still, they can at least drag the window left-to-right to see everything.
Alternatively, an extra tab. Redistributing advanced settings. The other three tabs could probably shrink a little without becoming cramped.
Or (third option), from Advanced Settings, remove the Flag Sets (unless anyone would miss it?) and shrink the checkbox list. This would probably be the easiest option, if also the least desirable from a design/functionality point of view.
Anyway, just tossing ideas around.
