InDesign AddOn – Page Control

I have always wondered why I could not have a variety of page sizes in Adobe InDesign. There have been times I would love to have completed an entire stationery system in one document; letterhead, envelope and business card to help insure consistency and avoid having to open and manage multiple files. Today I stumbled onto a company that has created the solution to all my page size problems in a plug-in entitled Page Controls ($59). From what I have read this feature is still not available in the new release of CS3 although I have not personally had a chance to try it out myself.
