The MultiEdit addon allows you to very easily edit multiple objects in a non destructive way.
This alpha version keeps the names, the materials, the vertex groups, the shape keys and the origin points(and I still could be forgetting something :D)
New video, with new features, thanks to Kilon:
(The video is not that great, I had problems with my video editing software. Also I tend to move in the 3D space very quickly, sorry for the headaches…)
Please test it and give feedback and suggestions.
I hope you find it useful
