What is your suggestion, and why should it be implemented?

Considering how many mods have different main menu background images, it would probably be a cool idea to let you swap between the ones you wanna use.

Could probably have different settings for it to like default (Sticks with 1 BG screen only), random (Picks a different BG screen every time) or even dynamic (Have it change to a different BG depending on which week you play)
