Github PR review is a Chrome add-on developed by aomega.co. It is a free tool designed to help Team Lead developers work faster with Pull Requests on Github. The add-on provides two buttons: "Approve" and "Cancel".

The "Approve" button fills the Pull Request description with the author's name and an approval message: "@username looks good :+1:". This feature saves time for Team Lead developers as they no longer need to manually fill in the Pull Request description when approving a request.

On the other hand, the "Cancel" button fills the Pull Request form with the author's name and a test to draw attention to comments: "@username looks good, just a few suggestions". This allows Team Lead developers to easily provide feedback and suggestions on the Pull Request without having to type out the same message repeatedly.

In addition to these time-saving features, the latest version (v1.0.3) of Github PR review includes a new icon design and a set of random messages on Approval or PR Rejection. These updates add a touch of visual appeal and variety to the user experience.

Overall, Github PR review is a valuable tool for Team Lead developers who frequently work with Pull Requests on Github. It streamlines the process and saves time by automating repetitive tasks, making it easier to review and provide feedback on other people's code.
