Concise description:
Some people only play cetain maps like i do, and at the moment i have to look through alL the games to find one i want to join out of those i play, therefore i suggest a new way of looking for new games via searching for specific maps.
HOW--- you would write the name of the game map you wanted to play in a search box and the game would find all games yet to start with that name.
To do this would require some code writting... which i know nothing about, so how hard it would be to add this i do not know.
made me look a right noob
