I'm interested in knowing what high quality and useful add-ons or utilities are available for TFS. They can be commercial or open source. Of particular interest are any tools allowing visualisation of branches and tracking changesets as they are merged across branches (yes I know that the next version of TFS will be better in this area). A lot of the lists of TFS add-ins I found via google are quite dated and link to non-existent / abandoned projects.
I'll start the ball rolling with two we've found very useful:
- TFS Branch History is an add-in for Visual Studio allows you to view the history of an item going back before the last branch
- TFS Power Tools is a collection of TFS utilities from Microsoft including a command line tool that provides several useful features
