From what i understand from the source now, you would have to also implement a function into the server, so that there is no conflict with modified maps... which might make it useless untill eihrul agrees (... which we all know won't happen, as it's an idea from the gaming world)
still, in my opinion, i think it's a great idea, some maps really need a remodeling.
I also think that when we are at it, one could adjust spawnpoints. Some are just placed on seemingly convenient places that don't coincide with the gameplay the map offers, whatsoever.
