Hi all
Thanks for the feedback.
Since the add-on seems to interest at least a few people, I will definitely ask its inclusion on the community website.
Beforehand, I have to take into account some of the remarks; special thanks to Lukasz for all these points with details.
Some other points will be included later, e.g. the GUI to choose the function to patch that I had already in mind.
Cheers,
Cyrille
