Amazing Mumble Client! Two complaints: 1 Though I have authorization for my user I am unable to move/kick others. It worked in the past but something changed in this client. 2 The proximity detection feature is a complete waste of my time. If the app is running  even in the background  and I move a finger towards the proximity sensor then the screen turns off. I would like to disable this. I often use my browser or messaging app in handset mode.
