Hi Marco, I definitely agree that those are important features! However there are even more basic CAD things that MoI is still missing such as dimensions.

32-bit memory limits and the fragility of the Wineskin based Mac version were causing a lot of problems so those were even more basic things yet.

If you need to do complex hierarchical assemblies, MoI probably isn't the best suited tool for that area right now but there are many existing CAD programs that can do that type of work.
