It's pretty annoying in GitHub when you've got lots of files to review and some are large diffs generated automatically that you don't need to review. Speed scrolling means it's easy to miss the start of the next diff.
This script adds a link that takes you to the next diff to review.
Just copy and paste this script into your console when viewing the diffs tab of a PR.
