If you haven't seen the new TreeDiff, you can see a screen shot in Brian Harry's post about the new release. It provides a VSS-style project difference tool that allows you not only to see what's changed but also reconcile changes.
Tan Phan, a developer on the version control client team, has written a post describing how to customize the TreeDiff tool. He provides a link to Michal Malecki's post about a workaround for the get latest issue as well as how to fix the file extension filtering, change colors, and more.
