Mobile overlay UI suggestion

In the mobile overlay that came with the latest android update, if you tap on the circle you can see who is talking and who is on call and how many people.
(O|OOOO) I just want to say that the overlay is SNAZZY and I LOVE IT. One thing I want to suggest, if it's possible-- if you have more than three others in a call, it shows a +1, +2, +3, so on. If the call is at +1, could it show the other fourth person as opposed to the +1 circle?
