Type of Enhancement

Web Interface/Frontend

Describe the Feature/Enhancement

The author has noted that Audiobookshelf currently utilizes PDF.js for rendering PDF files. However, the customization options are quite limited—you can only zoom in and out of the page. Features like two-page viewing, vertical or horizontal scrolling, and other advanced viewing options, as seen in Calibre-Web's PDF viewer, are not available.

Are there any plans to introduce or enable these features in Audiobookshelf?

Why would this be helpful?

This is make pdf viewing experience a whole lot better.

Future Implementation (Screenshot)

This is how calibre-web's pdf viewer looks like. It is also using pdf.js

I love to see better handling for PDFs too! Exactly these features in particular: two page view (optionally with even page on left or odd page on left), and fit to screen.

Right now most of my PDFs open as in the video from @adityachandelgit above, where they display just one page in a small part of the center of the screen.

@danielsiwiec did you ever get a change to work on a PR?
