An anonymous status would be nice, can't say how often I'd use it. I've grown so accustomed to setting my status to busy for so long...

Honestly, I would love it if they had a Report & Mute function (so it doesn't clutter the blacklist & I don't need to remove names frequently). I know it would take time to implement and they probably have to find a work-around for the PS3, but it would still be nice.
