GitHub PR Templates is a Chrome extension developed by adam.h.lyren. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free extension aims to simplify the process of applying custom pull request templates on GitHub.

When working on large projects, it is common to have different areas or components, such as frontend and backend. Each area may require specific information or documentation when creating pull requests. GitHub allows users to create multiple custom pull request templates, but it does not provide an easy way to apply or switch between them.

GitHub PR Templates solves this issue by adding a dropdown menu to the pull request form. This dropdown menu allows users to easily switch between the custom templates defined by the project. The extension achieves this functionality by scraping the paths where the templates are expected to be defined and rendering the results in a native-looking dropdown within GitHub.

With GitHub PR Templates, users can now seamlessly apply the appropriate template when creating pull requests, saving time and ensuring consistency across different areas of their projects.
