@FelisDiligens thanks for the plug-in, it's working very nice!
I second the previous request/question, I have converted notebooks (based of a CherryTree DB), using a python script (GitHub - d4vydm/CherryTree2Joplin) but there are quite some HTML-to-MD translation errors, and I would like to clean-up certain tags across notes, eg. on a (sub) notebook level downwards. That would ease a lot of the manual clean-up.
Cheers
