Add '(dis)connecting' image, tho on fast devices you barely see it. Auto-generated resources dictionary for same
Added intent filter for BluetoothAdapter.ActionConnectionStateChanged  and handler for same.
Clunky implementation of getting connection state (only checks for first device connected)
Add (pending)intent to be able to turn BT on (when it's off).

There's a curve ball with turning it off again tho :)
Accidentally commented out state change UI update. oops!
