Two QOL uses I've found is concept indexing and excerpt formatting. Before/after engaging with new material, I'd generate a table of concepts and the pages these concepts are mentioned. Simple two column markdown table, nothing more. Second, for excerpt formatting I use a specific markdown format (add timestamp header, page number, and one/two keywords) to convert my highlights after running through a PDF. A more advanced use case is extracting the bibliography and building an inverted index of where each citation is mentioned (page numbers/paragraphs). You can then compute all sorts of concordances: which authors are referenced on the same page, what concepts are related, which authors/concepts are over/underrepresented, and so on.
