Simple idea, really. What if we could have a "Furniture Set List" for our houses/FC private quarters, the way we do gear sets?
I know I'd love to do some special things in my house (like a haunted house for Halloween!), but don't want to go to the trouble of setting it all up, only to take it all back down and have to put everything the way it was before. That takes hours.
Just one more option in the Housing menu that pulls up a set list much like the gear list. You pick your set, and BOOM! instant redecoration.
