> One pretty minor thing that bothers me is that the webcam and mic mute toggles and the hang up button are blended in and out on moving the mouse cursor during a call. I'd prefer to at least have the option to let the toggles stay onscreen as I tend to use the mute mic toggle a lot during a meeting.

Could not agree more. Also, the shortcuts to mute audio and video are multiple key combinations and differ across platforms (i.e. using the command button on MacOS and Ctrl on other OSes). Why can't they be a single key, like M to mute/unmute audio and C for the camera? Heck, maybe even use spacebar for mute/unmute since it's that key of a feature?
