The icons at the top of the activity pages are very helpful, and I’d love to see the same — tiny ones — next to the remote names.
I have similar components in each room, and if Roomie was the last app I used in the den, for example, if I next unlock my phone in the bedroom, and I see the DirecTV remote (my custom remote), I tend to start tapping before I realize I’m controlling something in a different room.
Without changing the header height, tiny icons representing the current room, placed in front of the remote name at the top, would be very helpful. 
Thanks!
