I like the idea, it would be a nice little addition, but I think it could wait until there are more maps. Although it may not be the point, it is a valid point. Once you play a little more, you will memorize the map names, especially with the number there is now. Should a map editor ever be implemented(don't turn this into a thread about that), this would be extremely helpful, but for now the name is enough.
P.S. Nivosus is small and snowy, Frostbyte is bigger and snowy, Moonshine is small and grassy, and Zenith Cauldron is a desert.
