what I really want is a LED status display built into the top edge of my laptop screen (visible from opposite side too) that indicates -- when I am on a meeting / when I am muted or unmuted / when my camera is ON. (I should be able to turn them off when i dont need them and also have a manual override to turn them on as well -- so I dont HAVE to indicate my true status publicly when I dont want to -- I might even tie it to work only when on office/home wifi only for instance)
In WFH situations this would be a life saver as other people in the house might walk into your room / across your laptop in view of camera / want to talk to you about random things .... If this kind of busy indicator is present, those people can be a bit more mindful of your immediate situation and avoid distrubance / embarassment.
