I thought it would be a good addition to have an option to allow people inside your house while you were offline. Perhaps you'd have to give a housewarming gift to get inside or something, and there would have to be something that prevented people from coming in and swiping all your stuff. Bigger or upgradable cabinets would solve this problem.
Also, I believe that friends should be able to get in whenever without knocking, maybe just with a notice showing up on your screen.
Thoughts?
