VSIX Explorer provides a WinZip-like utilitiy for creating, viewing, and editing VSIX files. VSIX files are the new deployment units for Visual Studio 2010 extensions. To launch the tool after install, go to the Tools menu and click on VSIX Explorer.
VSIX Explorer runs independently of VS so you can create a shortcut to the program directly. It will be located at %LocalAppData%\Microsoft\VisualStudio\10.0\Extensions\Gearard Boland and Mariano Blanco\VSIX Explorer\<version>VSIXExplorer.exe. The only caveat is that if updates are installed the shortcut link will break due to the version change in the path, which you would then have to update.
