the dude is just angry because nobody supported his idea,so ignore him.
as for the idea,its quite good,it could actually be useful.and why create a script for that?
i think they could just re-use the script for saving the mods....right?
also,adding to the idea,maybe you could assign an object to a key in the keyboard,and when you press that key,a copy of the object appears.it could be useful when creating a mod with weapons,or with more that 1 of the same object.
