Extracts annotations and highlighted passages in all .pdf files in a folder recursively and outputs them as text files with the same name and modification date

Hey, zotfile developer here. Does this also extract highlighted text? Just curious because I am always looking for other implementations that also extract highlighted text and they are pretty rare.
Thanks for the useful script!

yes it usually extracts highlighted texts but it depends on the application used to make the highlights, I think, and also some other factors like the weather I think.
