Mergefly is a modern UI for GitHub Pull Requests. Our goal is to remove all of the frustrations surrounding existing pull requests by putting developers in an environment where they feel the most comfortable with the most amount of information.
Pull requests should be small, surgical, keeping only the minimum required updates. This extension adds a button to Github's Pull Request page that extracts files from one branch into a new one, so you can submit perfect PRs, even if you didn't plan ahead.
