What it does

Written by AI from the README

Shows the comments on your PDF highlights, underlines and note annotations as cards in the page margin of Zotero's reader. Comments render as Markdown, can be edited in place, and sit on the left or right depending on where the annotation is.

Annotation comments normally live only in the sidebar, away from the text they refer to. This keeps them beside the passage, including in two-column papers. The interface is in English or Korean.
