In particular, I’m referring to doing so with Pathfinder and Starfinder books, but I’m sure the feature would be useful for all books and systems. I would like to make Demiplane my one-stop shop for DM’ing Adventure Paths for the Paizo systems, but, as far as I’ve seen, I can’t markup, highlight, or make notes on the sources in my library. I do that with PDFs that I have, but I would love to be able to do it on Demiplane instead.
Happy to pass along the request!
