Right now, if you change your color scheme in beamng, it doesn't affect the main menu. No matter what color you choose, it stays the same in the main menu. I would suggest that the color of the highlights also changes. Also, in the color picker, there should be an option to choose custom colors.
Saving preset would be pretty could, it's a bit annoying to have to change the preset everytimes a new update came out, especially since we have a lot of minor updates
