JakobFel: I do like the fact that the background image from games persists until you click on another game but sometimes, the background image of a game isn't super appealing as a background for the homepage. I'd really love if I could have an option for a default background image so that when I click off of a specific game and go to any of my libraries or the homepage, the background will switch to the default image.

It wouldn't even have to be a custom image feature. Just a cool, purple Galaxy background would be fantastic. Obviously, this should be a toggled feature rather than something everyone has to deal with, but I think this would be a really nice one to have for those of us who get a little OCD about this sort of thing.

cryotek: I'd like this a lot. Along with an option to simply have the background black or white (though you could do that with a custom image too I guess).
