The admin Live chat console now opens with a dark panel like the podcast recorder. It shows how many visitors are on the homepage, whether you are live, and one large red key to go live or offline. Each visitor has a link that goes to their box and puts the cursor in the reply field. A link flashes red for a new visitor or an unread message until you go to that visitor.
Your camera preview and the microphone and camera buttons sit beside the key while you are live. Going offline with visitors present now asks first, because it ends their chats. The settings are at the bottom of the page.
