About This File
This started out as all I wanted to do is make the background image, when selecting a game fill the whole space. So after looking at the default theme and the great LBPlex theme (credit to @Grila) I managed to get all the bits I preferred and made a theme to my liking. Hopefully your like it too .
And now with updates from the Default Plus theme (credit to @faeran).
**NEW** Now you can have any colour you wish by simply changing the "selected Item background" colour. (see below screenshot)
