What it does

Written by AI from the README

Reads PDFs in book order in Zotero's reader: two-page spreads with page order from right to left, plus an in-window full-screen mode.

Suited to vertical-text Chinese and classical books. It changes page order only and does not reflow text. Toggled with Ctrl+Shift+V and F11.
