Expand & Collapse is a free Chrome extension developed by achamsanjeevakumar. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. This extension allows users to expand and collapse code sections hosted on any GitHub platform.

Modern code editors often provide a useful feature that allows users to expand and collapse code sections, making it easier to navigate through large codebases. However, this feature is not available in the web version of GitHub. This is where Expand & Collapse comes in. This tool provides the same functionality as the code expand & collapse feature found in code editors, but specifically for GitHub.

With Expand & Collapse, users can easily expand or collapse code sections within GitHub repositories. This makes it more convenient to navigate through lengthy code files and focus on specific sections of code without being overwhelmed by the entire file. The extension supports prominent programming languages such as Java, JavaScript, C, C++, PHP, R, and Swift.

If you frequently work with code on GitHub and find yourself needing to navigate through large code files, Expand & Collapse can be a useful tool to streamline your workflow and improve code readability.
