I would like to see a nodes library. In the Advanced Material Room, right click in the nodes window, and have a library choice there under the New Nodes menu. I would like to save nodes there that I have set up. Even simple things would be a boon to me like a math node that makes an image negative. I just can't remember a lot of those things, and have to look them up time and time again. Why not name and save the node, and just add it already set up.

For the time being, why don't you do it, like I do...

I save all those small snippets of nodes as single materials to my library
and apply them to a hidden dummy sphere in my scene, then copy to the
material needed.
I am sure, provided one knows a little about python, one could create Wakros to handle this more efficiently.
