As a reviewer of a proof inside a proof collection, you can control whether the next proof you need to review automatically opens up for you after you have left your decision.
The next proof that opens automatically is the one with the earliest due date and time in the collection.

Step 1
After leaving your decision on the proof, set the auto-open toggle to off/on depending on your preference to automatically open the next proof in the collection.
