Git Diff Flex is a free Chrome extension developed by pbarnum, designed to improve the diff comparison experience on GitHub. It adds a draggable pane bezel between two files when comparing diffs, making it easier to read and understand the changes.

With Git Diff Flex, you can effortlessly expand or contract a side of the diff to enhance readability. This is particularly useful when dealing with complex changes that span multiple lines. By adjusting the pane bezel, you can focus on the specific parts of the code that you are interested in, without getting overwhelmed by unnecessary information.

This extension is exclusively available for GitHub and seamlessly integrates into the platform. It provides a simple and intuitive interface for managing and customizing the diff comparison view. If you frequently work with code on GitHub and want to enhance your diff comparison experience, Git Diff Flex is definitely worth a try.
