Hi Jacob, the problem with that is that the major goal for MoI is to be focused on modeling. And not only that, there is also a big focus with MoI on ease of use and a fluid streamlined operation. This overall goal is kind of at odds with jamming in tons of features for things that are not quite primarily in the area of modeling.

Maybe in the future some stuff like that could get added in as some kind of optional plug-in package or something along those lines.

I am interested in adding in some kinds of constraint mechanism, but the initial focus of that will probably be much more as a way to edit 2D curves and not on constraining inter-object relationships like you are describing. The kind of stuff that you are talking about sort of fits in more with a program that is focused more on animation or simulation.
