At the moment, if you add a comment to a line in a change-set (i.e. the code review functionality) it causes the page to reload. This means that any options (eg. ignore white-space) are lost, and you're returned to the top of the page. This makes adding multiple comments to a change-set very frustrating if the change-set is large.
Would it be possible to either write multiple comments without reloading, or at least have the page reload looking at the same location with the same options enabled?
