Have you seen PowerCommands for VS 2008?

PowerCommands for Visual Studio 2008 is a set of extensions for Visual Studio written by Microsoft.  You can see a full list at the link above.  What you won’t find at the link above (unless I just missed it) is a link to actually download the extension.  You can find that at this link over on MSDN Code Gallery.  If you have the Visual Studio SDK installed you can even pull down the code and take a peak.

In my opinion the Copy Reference, Paste Reference and Copy as Project Reference commands alone are worth the download.  Less time spent waiting on that Reference dialog to come up. I came across this tool via the Visual Studio Hacks VS Links series (thanks Darren!).
