OMG really??? I'm new here but this software is like version 9 and it doesnt have something like this? It's pretty basic to me if the material graph is the main option to pro edit a material

No, not yet
- unless KS10 has implemented something. I just have to do it manually, sometimes it's like untangling a bunch of wires. Once everything is organized it isn't too bad unless you duplicate a material with a bunch of nodes or accidentally hit the align nodes button.
And maybe I'm doing something wrong but, even if I organize it if I add a New material while being in a multi-material object, this will make everything all together again!

There is a way to turn off this "auto-align" or "auto-arrange" every time I add a new material?
Thanks for the quick replies guys!
