Zathura vs Calibre

Zathura is fast and can open a pdf file almost instantly.

Inferface is clean and shows only a small statusbar.

You can browse files via keyboard, using keyboard commands similar to vim (text editor).

Zathura will automatically refresh the view when a document has been modified. (By contrast, Chrome requires a manual refresh and brings you back to the top of the document so that you have to scroll back down).

No unpredictable window opening behavior like Atril. Together with it's easy ways to scroll and zoom, zathura is perfect for fast look through lots of PDFs

• recolor-darkcolor
• recolor-lightcolor
• recolor-keephue
• recolor-reverse-video
  (see manpage zathurarc)
  Also, proper dark mode: colors are grayscaled not inverted.

For example:

• pages-per-row 3 (3 pages next to each other)
• first-page-column 3:1 (for 3 page column layout: first page is on the left)
• page-right-to-left false (2nd and 3rd page are shown right to the 1st)

Unfortunately I haven't found a way yet to map these commands to a key. The ability to prefix a shortcut with a number argument would lend itself perfectly to achieve what I had in mind.

For example:
map <C-l> exec "termite -c ./termite_config --class float -e 'tmux new-session /bin/ranger $(dirname "%")'"
<C-l> opens ranger with directory containing the opened document
Other ideas:

• extract pages
• print pages

See man page "zathura".

But unlike qpdfview search will only operate on one tab instance.

Features include metadata editing and downloading, coverpage downloading., book tagging and categorization, webpage-to-ebook converter for popular websites, etc. Lots of plugins available to extend functionality.

Calibre is available for Linux, OS X, and Windows, 32-bit or 64-bit.

Calibre has an optional portable build that can be stored on external media along with the users library. It can then be opened from the external media on any windows device.
