Github Pull Filter is a free Chrome extension developed by arianitu. It falls under the category of Browsers and is categorized as an Add-ons & Tools subcategory. This extension allows users to filter out specific files in a pull request by specifying them in the pull request description using JavaScript Regular Expressions.

Often, when committing changes, users may include library files or reformat multiple files. This can be inconvenient for reviewers who are unable to collapse groups of files using a filter. However, with Github Pull Filter installed, reviewers can automatically collapse and efficiently review only the desired files.

UPDATE:

As of September 11, 2017, the extension has been fixed to work with the latest version of GitHub.
