Kirk:
Most Windows apps, and Windows itself, have some sort of "Arrange Windows" item in the windows menu. This usually either tiles or cascades the open windows in the app, sometimes offering the choice of a vertical or horizontal arrangement. This could be useful in PM to see more than one catalog at a time.
Other apps, Dreamweaver comes to mind, have preset layouts that you can chose from, with the main window in one place and various tool or navigator windows in set places. I think Dreamweaver offers 2 or 3 preset arrangements you can choose from to suit your needs.
Perhaps for PM, it would be nice to just arrange the windows and save the arrangement, with possibly the option for more than one arangement to be saved, and recall one when needed. Or even just a restore default button somewhere.
