On personal computers (laptops) I would like to see a ambient info display and/or edge lighting / indicator option that can be customized and conrolled by software.

One of the use cases i like is a visible indicator of when the Video camera/ screenshare or microphone is on -- and if the user wishes to, display that status (busy/on air) to others around them (like some over-the-ear headphones currently do).

It will serve was a reminder to the user themselves to be mindful of the cam/screen/mic -- and also to nearby people not to disturb them to walk into camera frame unintentionally.

I am sure there are tons of other uses for those willing to experiment.
