you stated that the goal of the Indigo team is to "Make Indigo friendlier for new users...". I'm not a new user but more of a hobby artist.

I know that the material creation is currently part of the exporters but a "unified" way for creating/tweaking/adjusting/assigning/saving materials/shaders from within the GUI would be helpful.
I liked the integrated material editor in the Radium renderer (it's dead now?).
Loading the scene and creating/adjusting the materials was a breeze.
I'm a total newbie when it comes to shaders so i'm only using "normal" materials. Some sort of "klick-together-your-own-shader" would be another useful thing for the not so experienced users.
