The option to create multiple copies in a single alt+drag action, similar to 3ds Max’s shift+drag function where it asks how many copies to duplicate, and each copy is offset by the same transform from the previous copy.
This makes using modular kits much faster, and works just as well with rotation and scale.
Examples of usage in 3ds Max:
I do realize it’s a tiny difference, but time does add up with this sort of thing.
