Suggestion 1: Add changeable TC settings just like brake balance in the F11 menu. A changeable maximum allowed slip would be pretty nice for some mods, as it'll make the racing more immersive/realistic. Another idea is to have mutliple TC "modes" that a player can define in the setup menu, and just change between those on the fly.

Suggestion 2: Add more hotkeys on the Controls page for stuff like brake balance adjustments, ARB adjustments and TC adjustments if implemented/available on the car of choice. Right now this is only possible through scripting, which is very not user friendly/annoying to set up
