I really love the way Logseq for desktop handles PDFs. That's the gold standard for me. I can highlight in four colors and add annotations wherever I want, and they're automatically pulled over into individual note blocks, which I can edit and tag alongside the doc. If I click one such note on the future, it opens the PDF and shows it to me in context.

But PDF annotation doesn't work in the mobile app. Omnivore is the closest to similar functionality for web articles that I've used so far, but scrolling vs. turning pages makes a big difference on the ereader's screen.

I actually used Calibre to convert all my epub books into PDF, and I try to read them on a convertible HP tablet/laptop I coerced into running Linux, which I can highlight on with a compatible pen, but it still leaves a lot to be desired.
