The SharePoint Service manager let's you start and stop all the SharePoint 2010 services on your workstation.
This is useful if you are running SharePoint 2010 on Windows 7 and don't want SharePoint to slow your machine down when it's not really needed.
See http://merill.net/category/service-manager/ for more information.

Here are a few screenshots from the latest release.
