Hi Michael,
I really appreciate the effort you put into moi.
I am sure it is important to have a strong basis.

I just think that, with layers (which can also be exported well) I would switch for 80% of my modeling work to Moi.
Because I deal with large architecture models, I need to have a way to manage complex hierarchies.
It might be different for people modeling industrial products ,but if I have hundreds of objects and I need to export to an external app a few time (also back and forth), then scene organization is very important.
