Another update. Now I know why I have avoided to mess with the GUI. It's a friggin time eater.
The idea is to speed up track/car selection. There will be support for page scrolling to left/right or top/bottom. The background will be the selected track(loading in the background, lol).
I'd like to use the same idea for cars too. Showing car side view outlines(blender can render them). What do you think?
Sorry for the ugly look, just a quick job for functionality testing. The cancel thingy is also temporary.
