GitHub Quick Preview is a free Chrome add-on designed to enhance the user experience on GitHub by allowing users to quickly view the details of Issues and Pull Requests (PRs) without navigating away from the current page. This tool is particularly beneficial for project maintainers and developers who need to manage multiple issues and PRs efficiently. Key features include an inline preview button for easy access to comments and details, as well as support for both HTML parsing and the GitHub API for versatile functionality.

Additionally, GitHub Quick Preview automatically adapts to dark mode, providing a seamless experience across different themes. Users can utilize this tool by simply visiting any GitHub repository's Issues or PRs page and clicking the preview button next to each item to see detailed content. As an added benefit, the add-on prioritizes user privacy by operating solely on the GitHub website and not collecting personal information.
