http://reviews.reviewboard.org/ What version are you running? 1.6.3 What's the URL of the page this enhancement relates to, if any? It relates to the comments/issues on a review request. Describe the enhancement and the motivation for it. When a comment on a diff is posted against a review request it typically means I expect a change to be made, especially if I mark as an issue. When the review requester updates the diff and/or marks the issue as resolved I would like to be able to see the resolution in the new diff. In a large diff it can be slow to locate the corresponding code and to cross reference with my comments. In the general sense I'd like to be able to view a 'diff of diffs' or 'corresponding diff' for any areas I (or anyone else) commented on in the new revision. What operating system are you using? What browser? I'm using Windows 7 and Firefox 16.0.2 Please provide any additional information below. I believe this feature would improve the user experience around iterative reviewing of large change sets under ReviewBoard. At present it is functional but can be a little frustrating.
