Hope this wasn't proposed already.I think it would be handy an internal application that when launched syncs players maps to see (already in the map selection) if users have them or not.When having lot of map it takes a while to find one that everyone have since not everyone have a fast/stable connection for downloading them on the fly.
Sorry for my english but i'm a bit rusty =P
