Addon idea

Unless I’m just stupid and dont know how to do it. How do you save nodes setups? I went to th side bar and nothing showed up that would be related to it.

Node groups saved inside .blend files are accessible from other projects. Just use File > Append, and navigate inside the first .blend file and into the NodeTree section.
Once appended, a node group can be added from Add > Group menu.
It’s not exactly like having presets for each node, but this way you can create your own templates and just add them from a library blend file.
