My app building yielded the v0.8 version of the VSCmdShell Window add-in.  If you haven't been reading my blog your wondering what the hell this thing is so... The VSCmdShell Window is a tool window for Visual Studio that creates an instance of the cmd.exe shell running inside the IDE.  It also allows you (as of this release) to run Visual Studio commands from your current directory.  Check out the screen-shots below for more details and send me any feedback you might have.
