When choosing a background image, it's not yet possible to just have it centered in the background, and keep it's aspect ratio. Should be simple to implement.
Furthermore it'd be awesome to choose the size (e.g. 123%) of the image, so that the user doesn't have to change the size of the image manually. Even better: %-size of display width (or heigth).
Use case: have company logo (or fictional company logo like Weyland-Yutani-Corp from Alien or Cyberdyne Systems from Terminator) centered in background.
