Does it give you a way to link a fragment of text in a PDF to notes about it somewhere else and navigate between the two? This is the biggest pain point that I basically solved manually in my PhD with a kind of made up system with hash tags embedded in PDF notes. It's such a painful process maintaining a collection of citations around a particular topic, and being able to map what papers support what pieces of knowledge along with context around that. Still seems relatively unsolved problem to me.
