Currently there is no easy way to see which files are actually changed by a patch set. E.g. one has to go through all the files one by one to see whether the file has been actually touched in the last patch set, or in another one.

E.g. have a look at http://codereview.qt.nokia.com/#change,217 . The patch set 3 only changed the commit message + one file, but there is no easy way to see this!
