What it does

Written by AI from the README

Detects white margins on PDF pages and fits the actual content to the window with Fit Width and Fit Height buttons. Adds page-by-page navigation and a button to cycle Zotero's single and spread layouts.

Large or uneven margins make text look small. This enlarges the content without cropping or changing the PDF. Built for Zotero 10 and replaces the Reset Zoom button while active.
