Cool Designer Trick for Panels

As far as I know, the VS2005 "Designer Tool" cannot be used with the System.Windows.Forms.Panel class. This can be utterly frustrating when doing layout. So, what I do instead is, first, rename my System.Windows.Forms.Panel derived class to extend System.Windows.Forms.Form. Now I can do my layout with the handy visual "Designer Tool" -- e.g. I right click on the source code and select "View Designer." Once I'm done adding widgets/controls and laying them out, I rename the .Form back to .Panel. Tada!
