[Describe the enhancement and the motivation for it.]
Individual reviewers should be able to "archive" reviews after finishing with them. Once a reviewer archives a review, the review should disappear from the reviewer's dashboard until there is a further change to the review (e.g., new comment, diff, etc.).
The idea is very similar to the archive feature in Gmail. There, once a conversation is archived, it disappears from a user's inbox until there's a new email on the thread.
The motivation is usability. Currently, reviews disappear from a user's dashboard only when the submitter has decided to mark the review as submitted (or discarded). There is a particular problem when submitters forget to mark a review as submitted; currently, the only solution is to nag the submitter.
The current approach seems backwards: it should be up to a reviewer to control what reviews show up on his/her dashboard.
