I don't think we really need it, but I bet it'd be cool to have some kind of opening artwork to give a level some opening atmosphere or an initial idea as to what the level will be/look like. This image could appear on-screen as a banner, or maybe even fully on-screen just before a level starts loading!
Of course, if this were to be implemented, it would probably be much less confusing if custom images were used, preferably by file. What else could work? :3
