I've been using this app for years on different devices alternating with other pdf/djvu readers. At the moment it is my main app for reading these file formats. Fast and uncluttered, it has all features I personally need.

I downloaded this to crop pages. ALL pages must be done together. The one to treat even pages might as well not work because it produces random behavior. Auto crop chooses 1 pages at random to be good with and you can't manually adjust any of the pages alone--so you're praying the one it does pick isn't garbage

Thank you for your feedback! Just to clarify possible issues with cropping we should mention that Orion support different crop modes: one crop parameters for all pages or different crop options for even and odd pages. Orion also support experimental auto crop mode where borders on each pages cropped automatically without influence to each other.

Good progress being made with this app, and an up-to-date PDF + DJVU reader with issue-free external storage access is sorely needed. This fits the bill. Kudos to the dev!
