Hi 2byts, I'm glad that MoI is useful for your hard surface modeling!

I definitely want to improve the object organization tools, you can use Styles currently as a similar mechanism as layers, but in the future I want to add other methods that will allow hierarchical structures with groups and instances.

It will be a while yet before I'll be able to work on that, I'm still in the middle of a major rewrite to get a 64-bit version first.
