BIG ROUND PTT button in the MIDDLE of screen.

Suggestion.

Make PTT button in android app big, round and place it in the middle of the screen, like in Zello mobile app. Current position and size makes people press "home"/"back"/etc. while they not watching at the screen. I guess BIG, ROUND button in the MIDDLE of screen will be "hard-to-missclick" thing :)

And/or add an option to select between "legacy" and "advanced" design.
