Comment 4 for bug 609297

+1. How can this feature request be low priority. it is an essential feature to really do code reviews! github gets this right and there is even Rietveld (codereview.appspot.com) which is aweful looking but functional.

In launchpad I have to copy and paste the line i am revering and/or constantly scroll down and up between textbox and diff - not very pleasing at all.
