I think we ought to be able to re-arrange the furniture in houses, as well as the furniture we build. Perhaps we could make furniture heavy objects (That is, impractical or almost impossible to move while carrying -anything- else, so as to dissuade people from hauling a couch up the stairs of their fort.) so we can set them down in other places? An idea occurs to me to treat them like carpentry crafting recipes in that they're the ingredient to place themselves. Obviously, no skill associated with doing so, but the whole rotate/set functionality... How hard would this be to do?
