Button to add a reviewer

[Tyler Butler]

When viewing the home page of a review and attempting to add reviewers, it feels very unnatural to have to go to the upper righthand corner of the page and click on 'Edit Details' to add a reviewer. I had to remind myself several times that the Edit Details button was the one to click for adding a reviewer. Having an "Add reviewer" button or something similar at the bottom of the list of current reviewers seems like a much more natural place.

This is a quite good idea. Bitbucket has something similar. You may want to raise an improvement request in https://jira.atlassian.com/browse/CRUC.
