I’m suggesting that when someone opens your cam, their name/icon moves up to the top of the listview under a “Who’s Watching Me” section so you can easily see who has your cam open.
Yes, I know that you can see the “glasses” when somebody is watching, but we old people sometimes have a hard time seeing that.
…Then of course this would mess up the “visible” and “hidden” user grouping, so you might need to have a setting for people that like this grouping. This is why I hate programming – you can do too many things for too many people.
