What does it mean that the audio and video pod is floating?

It means that you or your attendees can unpin the pod and pin it in your preferred location for better focus.

Please note that you cannot maximize the audio and video pod to the full screen. To enable it in the main presentation window, go to the Dashboard and enable AV View. Remember you can also pin your camera stream to the bottom, for a better focus on other presenters’ or attendees’ faces. To do so, click the appropriate icon available in your stream.
