I LOVE the idea of supervising our house and resources from a mobile app. It would totally give it a nice life to the housing and we can always take care of our things, anywhere, anytime. Having like a second game in our house, managing resources and building our own "land" would be a great addition.
Maybe we have the house for housing, furniture and so on, but then around the house we can have different land ideas. Shore for pirates, cave, mountain... Each house would be in a different biome. The house could be used in game for roleplay or whatever event we want to make there with other players, and then a small nature place outside to manage things in the mobile app. It might be hard to achieve it but at least the idea sounds AMAZING! And give the life to the housing that no game achieved.
I agree, that if make that in the mobile version, the game will much much more alive and interesting. We will for sure discuss your idea, when the time comes.
