I really like the add-friend buttons that appeared on the site a couple months ago. What would be even cooler is when you click on one, the page that appears contains the option to place the friend you are about to add in one of your premade groups. It's kind of a pain to add a friend and then go into your client or a separate page and then put them in the appropriate friend group. It would just make things more streamlined and easier for us organization freaks :)
