git-expand is a free Chrome extension designed to enhance the user experience on GitHub, specifically when navigating pull request pages. By automatically detecting pull request URLs, it activates a user interface that scans for hidden content and conversations related to the pull request. The extension ensures that users can easily access all relevant discussions and updates without manually searching for them.

The extension operates seamlessly in the background until it identifies a pull request page. Once activated, it displays a floating message that informs users about hidden items and allows them to reveal this content with a single click. This process repeats to ensure that all hidden elements are uncovered efficiently. If no hidden content is detected, the UI remains unobtrusive, ensuring a smooth browsing experience.
