Hello,

Would it be possible to use, in the World editor, the +1 button of the duplicate function to copy/paste the selected object a the very same place ?
This would be very usefull to align elements quickly

And maybe a little magnetism to glue close elements ?

Hm, true seems EE has removed CTRL+C/V so this would be good to have back(honestly been along time since I used the world editor).

What do you mean glue close elements? user created Object groups?

Nope, I thought about translating the selected element to the closest one so that their bounding boxes make contact.
