Previous / Next Revision Navigation

[harrisric]

When reviewing code it is useful to be able to step forwards and backwards through the history for that file. This might be either as a whole file view (potentially with the blame annotations) or as a difference to the previous version.

It would be helpful for;

• the main code review screen to have previous/next revision buttons
• difference view to have previous/next revision buttons. This could be limited to the case where you are comparing adjacent revisions from the history.

The main code review screen almost allows for the navigation to previous revision via use of the blame annotated view but this only really works when you are using a version control system which has sequential revisions (such as SVN) rather than one which uses non-sequential hashes or similar (such as git). In this case the user can look at the annotations and select the previous revision to step back (obviously can then reverse that by use of the browser-back).
