Oh man, I do miss the original Sims where you could just like ctrl + drag a floor and have that piece disappear xD
I get that they need the rooms to define inside/outside for weather and whatnot, but I mean, a room does not even seem to count as an inside room anymore (roof clipping starts happening) when you add a fence that touches the wall or a platform or a room with half walls or no walls.... I wish we could just define our own rooms as inside or outside ... (I mean, bet we would all love to see a fenced deck where it remains 21°C even if it is freezing outside :p)
