You could have downloaded Intelligent Windows 2.4 for Mac from our application library for free. The application is included in Theming Tools.
From the developer:
Intelligent Windows allows you to set buttons on the utility palette that record the location and size of any application window, including the finder. When you set a window sizing button a small proportional image of your window is drawn on the button so you can easily identify the window. It is incredibly easy to use and handy for keeping your desktop organized.
