This script will allow you to send the selected objects to UVLayout and get them back.
This is useful when you wants to have more than one object in the same UV square.

It’s a modified version of Norman “Norman3D“ Schaar’s script, which is modified version of Robert Fletcher’s script.
You can find the script here:
