This repository is an enhanced fork of the official Google Scholar PDF extension, based on version 0.4.10. Thanks for Google team's work. Hope this extension will be helpful!
Hover over any Table, Figure, or Appendix reference in the main text, and the corresponding item will automatically appear in preview mode. You do not need to switch pages. A toggle button is also provided to switch between preview mode and page-jump mode.
You can now display multiple preview windows at once and drag them freely.

Hover over an author’s name to preview their Google Scholar profile. Click the preview to open the profile directly, with no need to search for it yourself.

Display two pages side by side for a more comfortable reading experience.

Keyword matches are highlighted directly on the Chrome/Edge scrollbar, allowing you to quickly locate relevant sections throughout the document.

Annotate PDF files freely with a built-in drawing tool.

Coming Soon!
Note: If you have the original Google Scholar PDF Reader extension installed, uninstall it before proceeding.
