I'm not sure if this has been suggested before.
I'd love to see different versions of the Carpet or Chess tiles. Even different shapes and colors of Wooden flooring, like one that is well organized and defined(maybe birch looking).
It'd be nice, it would compliment the aesthetics of whatever event skins are getting sold at the moment, like some victorean themed carpets(well.....uh...MORE victorean themed carpets), you know.
