I think that floor plan is in everybody's top 5 most wanted features.
Apart from that I'd personally like more use of gestures; now we have a swipe up http works great, but why no swipe left/right to switch panels? Or to switch units on or off? As it is now if I want to switch a unit I have to tap once to get to the control section, once on the control for the unit to pop up and finally tap on the on switch. I could just swipe right to turn on and left to turn off. The panel change could be a two finger swipe left right in this case.
Also I'd recall my old request about the buttons being accessible when a camera pops up, the ability to send mail or notifications (I'm still looking forward for possible uses of the iOS 7 multitasking I asked about some time ago - maybe some notifications when events occour?).
Also the direct ON OFF buttons I requested a while ago.
I'll have a ton more requests, but I'll leave to that for now.
