It would be cool to have an option to add an icon by your name, similar to the friend icon, to show status at a glance. The main function would probably be to let other people know you're recording for YouTube or streaming, so you're not recording without knowledge and they can avoid you if they want. Could be some other functions too, like to show you don't have a mic.

This would be different than changing your username or avatar, like a few different options that you could just check a box.
