Hello!!
I'm a new user here and i've some question. I've download a lot of great plugins from here.
I Just watched a 3D tutorial video and see something interesting about the toolbar.
I've capture the toolbar image and i'm very curious.
Here are the image.

Hi, those are plugins:

1. Skin;
2. Subdivide and smooth.
   Anyway, if you are interested in Subvide and smooth I suggest to buy Artisan instead by the same author. It's a lot better.
