Mute all is enhanced to enable moderators to mute everyone with a single click then designate a speaker.
Moderators see the mute all function at the top of the participants list:
Click to mute all of the participants. The cursor changes to select speaker when hovering over a webcam participant:
Select the participant webcam feed of the designated speaker to un-mute the speaker.
While mute all is set, all webcams set as live are automatically muted when they are added to the stage. Moderators can un-mute additional speakers to enable a select few to speak to all the participants.
Turn off mute all mode by clicking the mute all button again. All webcam feeds on stage are un-muted.
