What it does

Written by AI from the README

Keeps rendered PDF pages and loaded PDF tabs from being discarded when you switch apps, desktops or tabs. Optionally pre-renders a whole paper and retains pages as you read, at the cost of more memory.

Returning to a paper in Zotero can force pages to redraw because the reader drops its canvases or unloads inactive tabs. This trades memory for a paper that is ready when you come back.

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews.
