One thing that is a bit annoying is there is stuff that shows up in the Workshop Queue that is already in the game. Ether the item got resubmitted to be put into a tournament (Like the sets in the Beyond the Summit Chest), it could be part of the set that got in, but never formally marked as accepted (Like the custom icons), or it could be a style to a set that was accepted, but the style wasn't (Like the EG Naga set for example).

I just don't really like seeing things pop up that have already been put in the game or passed up on, where I could be voting on new things.
