I know its going to sound like a corny idea, but something I'd enjoy seeing in the next Live update would be the ability to pick 5 of your achievements and have them displayed on your gamercard, above or under your name. Just so you could have the 5 ones you like the best prominently on display, instead of just hidden in your games list.
I mean, who wouldn't want to display their "Suicide King" achievement?
