Let me clarify.
If you do a bunch of multiplying, it would help to lable each multiply node.
"FunkyDiffuse_X_BlinkingEmissive" 
"Mask_of_Effects"
"Remove_Red"

There's nodes like "node_394" that make it hard to track what's going on if the shader is even slightly complex.
Great, incoming values have readable names, now do that for arbitrary nodes so they are easily found in code please?
