Hi NightCabbage, actually your example of a bunch of houses kind of brings up another issue, which is how much does an instance system really belong in a modeling-focused application.

When you mentioned having a bunch of houses and changing one would change them all, I guess I would wonder - would you really be using a modeling-focused system like MoI to arrange a whole bunch of houses like that? Making a kind of big scene with a lot of repeated stuff in it is kind of something that goes along more with a rendering or animation type program instead of MoI.

One thing that I do worry about is trying to jam too many sort of semi-unrelated functions all into one single interface, it is hard to do that and also maintain simplicity at the same time.
