GitHub Superfilter от Tomer Ron

GitHub's default pull request filter sucks! It only allows to filter by file extension, and it doesn't properly handle files with multiple extensions (like .test.js)

On the other hand, GitHub Superfilter is awesome!

• It gives you more control over how you filter your pull requests. You can search for files in a specific folder (/components/), or with a specific extension (.test.js). You can also filter out files (!/src/ or !test)
• It's lightweight (< 4KB), only runs on github.com, and does not make your browser slower
• It helps you become a better developer by making your life just a little bit easier
