I've always had a problem with MMF2's 'create new objects' event.
The reason? One must select from a list the object they wish to make. (you can just use fastloops for the same object, but that's not the point.)
The problem? Say you want to make 500 different items during runtime. That would mean you would need 500 events.
Solution? I simply request an object that can use the Expression Editor to create new objects. Meaning, you can create 500 individual objects in 1 event. Far more convenient.
I'd also be happy if this was just included into a upcoming update instead of an object.
