I've been noticing on the last few PDFs I've purchased that none of them have been tagged or marked to make them more screen reader-friendly. I'm not sure exactly when this started happening, I think the first place I spotted it was in Highhelm, but it could have been going on earlier than that.
Does this mean Paizo isn't tagging their PDFs anymore? They're still plenty readable without it, but it was a helpful feature that could sometimes circumvent odd layout issues that trip up my screen reader, and also meant that scrolling past the abridged table of contents, along with my watermark, on every page was a non-issue.
