I have found several great eReaders for PDFs that feature bookmarks (free and paid), text reflow (free and paid), night/dark themes (paid only); but I have yet to find a single PDF reader that can actually change the font face. At the very least it is not a feature worthy of listing in paid apps.

I am wondering if anyone can recommend an app that meets the above criteria. I've attempted to utilize pdf2html.com, then github, then rawgithub.com, then readability to gain the features I'd like, but truthfully, it's far from perfect. The readability app has no bookmarks, so at this point it's more of a novelty.

Any assistance is appreciated.

Thanks very much,
