The new microphone Icon for the Desktop UI overhaul is REALLY hard to see when you are actually talking. I believe the values are the same from the original UI however due to the top right position it is now a lot less obvious when your microphone is picking up audio.

I don't want to claim a fix but an Idea I had was for the mic itself to go green or something like that to make it obvious when you are speaking.

It just needs to be much clearer, as my first reaction when seeing the UI was not knowing if my Mic was on or not.
