I use this tool to find/manage some script by avoiding all the color node, by put them in black. Few python buttons from a panel will permit to select some specific nodes as few categorizes.
 Download the toolkit :
- readMyScript.py
- menu.py
- install.txt
Version up by cleaning up the python code, to make it more efficient.
