## What it does Goes through the pull requests sitting in your queue and sorts them into what can merge now, what still needs a review and what should simply be closed. The point is to arrive at a queue you can clear rather than a list you keep scrolling past. It runs on a schedule rather than waiting to be asked. ## Before you install Open the share link and read the instructions it carries before you add it. Claire shared this one publicly, and adding it copies the setup into your own account rather than giving you access to theirs.
