What do you guys think about option to select which wallpaper you want to use?
I mean what wallpaper from installed schemes. That way you could select to use for example Pleego as color scheme and then choose to use wallpapers from DeepOrange etc?

And ofcourse there would be an option NOT to change the background at all if you wish to keep your current self-set background to be active after setting the color scheme.

I'm not yet sure how will I do the last part, but the first one would be easily doable.
