GitHub Code Review Helper is a free Chrome extension developed by moshe.zemah. As an add-on in the Browsers category, it aims to enhance the code review experience on GitHub.

One of the main features of this extension is the addition of a files tree on the left side of the files diff in GitHub. This tree allows reviewers to easily navigate through the files, mark them as "Done," and collapse or expand all files as needed. This feature greatly improves the efficiency and organization of the code review process.

In addition, GitHub Code Review Helper offers several other useful features. It makes the files header sticky, ensuring that reviewers always know which files they are looking at, even when scrolling. It also provides a shortcut to jump directly to the "Checks" part of the conversation section in a pull request, eliminating the need to scroll all the way down. The "Checks" list is conveniently positioned higher, reducing the need for additional scrolling.

Furthermore, this extension enables reviewers to jump to the next or previous diff file and easily navigate between code review comments. Under the "Files changed" tab, reviewers can quickly switch to the conversation tab with a single keystroke, eliminating the need to scroll all the way up. These features streamline the code review process and make it more efficient for reviewers on GitHub.

GitHub Code Review Helper is a valuable tool for anyone involved in code review on GitHub. With its intuitive features and seamless integration, it enhances the overall code review experience and improves productivity.
