I was leafing through the Animal Crossing thread and saw Alain mention that his friend code was on his profile and thought it would be neat if, instead of having to maneuver to a different page to find his code you could highlight his avatar for a second or two and little bar would come out (covering the date of the post) with his friend code for easy access. It'd only save a couple seconds but it's convenient..
