I think grouping the games in the waiting room according to game type, instead of alphabetical, would be a great idea. But I personally like being able to see all the available games on ONE page.. Or maybe an option to check off the specific games you want to see everytime you enter the waiting room, (with the option to "see all games").

OH, and I don't know what "rollover unfolding to submenus" means, but maybe if someone describes them, we webtv users can tell you if we have seen that sort of thing working for us. A lot of times things don't work exactly the same for us, but do, in a modified way. One example is when on a computer you click something and it brings up a new "window", on webtv, some of these are handled by putting this new "window" at the bottom of the page.. and the screen scrolls down to it, and if you scroll up, you see the original page you clicked off of. (Not that any of that has ANYthing to do with the "rollover unfolding to submenus" thing, just an example as to how things sometimes work differently for us.. lol)
