Simple Request - ObjectDock Properties

It would be great to have the option to show "open window thumbnails" (Vista and higher) under the "show 'running' indicators on shortcuts that are already running" dropdown menu. Or, in other words, the result would be that when a program shortcut is opened, the icon for that shortcut turns into a thumbnail of the open application window. That way I could reduce the need to display open windows along with my icons, thus reducing the size of my dock.

Thanks.
