As far as I can see, this has not been mentioned here before:

The workflow is mainly aimed at legal professionals

"Import all the documents relating to your case, organising and updating as you go.
Use the comment, highlight and link tools to review the evidence and build your case.
When you’re ready, paginate your digital case file, ready to present as a court bundle"

but could be of use to others, e.g., for Qualitative Data Analysis.

Thanks to Joe Bellavance for the heads up.
