One point I'm not sure is directly related to the extension is the fact that too much AI-images are not "flagged" correctly as AI, so this extension misses them completely. I estimates that only 1/8 images IA image I have are spotted due to their wrong labelling.
two other points are well related to the extension: the extension needs a manual start and put 2 icons on the screen of pinterest, both hiding some useful element (one hides the start of the search bar on pinterest, the other hides a big part of the last image on the first row of display).
I hope it will be corrected.

Amazing
