[Debug] Create a "print" node

Hi ! I'm learning shaders through your plugin and so far that's very exciting !

But as a beginner, sometimes I don't understand what's going on with my nodes, it will be VERY helpful if you could add some "print" node that will simply display the input on the editor without doing anything else.

I searched a bit on google and on this site about this feature, but I didn't find anything like that.

Please close it if you already know a similar request.

Thanks !
