ok what i think would be a great idea is a kind of new world but its made of houses that people own and have designed.
it wouldnt be your house that is sent to that world it would be a copy of your house that could be updated if you remake your house or add something new.
now i know not everyone wants a copy of their house for everyone else to see so it would be optional.
KI i think that a world made of copys of players houses would be a AWESOME new addition because then people could go around and look at other houses that people have made and get new ideas from them.
