I have no idea if it was ever suggested, but what I mostly want to see, is that you can unlock other houses, not only yours. Also to that topic the ability to change your password on your house, becouse you might want to change it after giving your password out, or just currently you have a very easy password.
In the current state I don't see why is there even a password on your house and garage, since only you can get access to it anyway.

More ideas will come soon, I would like to hear others opinions as well.

there should be a "guest-access" for my house, so one of my friends can unlock or lock my house when im not online or whatever. (just a menu like stronghold)

the rest is fine, like it is now.

Yeah, if they make it all public again I would definitely say allow the ability to change lock codes. Would require a new tool like a "Electricians Kit" or something.

Guest Access has always been something I've desired. Even if not for full house access, I would like to be able to let my friends have some limited access.
