I just found this addon while looking for tools to help me debug how Outfitter is taining the UI and causing the pet bar to not display when the pet is called in combat.
Since this happens simply on loading Outfitter, the diff was huge - larger than the chat window could display. I updated the .toc and the .lua to save the tainted data as saved variables, as well as the clean data. That let me scan the tainted items with a text editor.
You might want to make this change in the "official" version.
