You mentioned you haven't used the stars for friends. Starring is helpful if you keep inactive friends so you can keep your live friends separate from the zombies.

Also, you may notice FOUR sets of friends that way if you don't remove anyone. (ie. Starred active friends, starred inactive, no star but still active players, finally unstarred and inactive zombies).
