The attached project allows you see what a form looks like at design time without having to open the form in Visual Basic (and avoiding the errors that get thrown if you have anything other than intrinsic controls on it)
You can open and preview multiple forms at once. MouseOver a control to see it's name and type (if it's not displayed).
The GUI is self-explanatory. If you have any questions / suggestions or spot any bugs then let me know here.
