So with the implementation of personal housing, I have spent a lot of times going through houses to get some cool furniture ideas and see what others have come up with. The only problem is that a lot of times, people aren't home! I think it would be a good idea to add some sort of sign-in book as a tabletop item or something like that, where people can interact with it and leave a brief message for the owner. Whether it's an "I came to visit you" message, or an "Oh wow, I like this furniture combo! Good job!". I don't know how difficult it would be to add something like this, but if it's at all possible, I think it would be pretty neat.
