Just an update, I have to take back any (mild) frustration I had about the way that MoI nudges users towards relying on the graphical snapping system as opposed to edge-default or manually-specified snapping. The UI ergonomics are really fantastic! I particularly love how much I can rely on the 3D view alone for modelling and not have to spend as much time in 4-panel for design work. I usually only do this when dealing with animation material.

The only things I really wish were in MoI are a node-visualizer/editor for the scene-graph (along with individual node histories) and Python scripting.
