Similar to how you can see requests you already put in the system, it would be helpful for reviewers to see a list of reviews they've already completed and what approval (or non approval) they gave. We have some reviewers that review many items each day and sometimes they can forget they already completed a review. Rather than have them have to ask an admin or search through their email for the original request to review they would be able to see that they reviewed and approved it (or not).
