I am a big fan of the web site MacWorlds Mac OS X Hints and check it daily for helpful new tips. Today I found an excellent tip that allows you to preview the 10 most recent documents opened from within the Preview.app. To access the last 10 most recent documents opened from within Preview.app you just use the gesture: slide 3 fingers down your trackpad and the last 10 most recent documents will appear in a Cover-Flow like effect allowing you to select any one for opening in Preview.app. This same gesture just happens to work from within TextEdit showing the 10 most recent text documents.
