Useful UI adaptation

Add to the UI voice limits. Now that we have at least some of us the ability to use conversation mode, there should be a little ticker somewhere in the UI that shows you how long you have left. The reason I would implement this is because right now unless you know a way that I'm not aware of, there is no way to know how much voice you have used and how much you have left. This could become a problem if constant use is being done. It could result in sad feelings when you expect to have a voice conversation but can't have it. I would suggest adding it directly into the profile so you can see it. Maybe somewhere in the settings
