Boot and Mute
* Users can now boot viewers off their camera. From the viewer's POV the booter has just turned off their camera and it will remain "off" for the remainder of the booter's session. * Users can now mute one another: if you mute a user, you will no longer see that user's messages or DMs; and the muted user will never see your video as being active (like a boot but revokable if you unmute later).
