I disliked them for a reason. If I've thumbs downed a map for whatever reason it means I don't want to play it. It's annoying to have to exit to the main menu after a level I did like in order to select another one when I'd rather just play through the suggested maps or whatever.

On a related note, maybe add an option to "rate and skip" or just a "skip" button would be nice when going through the suggested map rotation.
