Something I've always wanted, and don't know if it will be possible with the engine changes in V11, is realistic load distribution, or at least a little toggle.
So basically, you'd have to build something that's structurally sound (I.E. No bridges comprised of 2x10Fs with two studs of overlap) AND bricks being able to support 'weight'.
So essentially, if you build a mindforget of a house, it would actually collapse.
