I think it would be a wonderful idea to have a search field for game numbers in the game menu (or anywhere in the left side tool bar). That is, when you go to the actual gamefinder page, the first criteria to search for is "Game Number". If this were in the game menu, beneath the gamefinder link, i'd be soooo happy. (if you get that SouthPark reference, you're very cool)
Games could be opened in a new tab window.
It'd be 10 times easier to pick up a game, when in callouts or chat!
