Hey BigMarker team, it would be great to be able to control what attendees see, basically actively choose what is going live during a webinar. Sometimes you want to set something up in the background, such as a presentation, or simply check on something, while a video is running or you are on the camera tab. Currently, the attendees see if you switch to another tab, and that is not ideal in all circumstances. So, it would be great if you can freeze/pause the view screen for the attendees while arranging things in the backend.
