Bookmark words in Apple's dictionary.app

I feel it's worthwhile to continue this discussion.

Not only would I like to bookmark words in the Apple Dictionary I would like to be able to use the built in screensaver that uses those words. Apple already has a piece of this, "Word of the Day - Screen Saver", but they are random words. It wouldn't be a far step to allow us to create our own "Dictionary" of the words we have bookmarked, sort of like an album of words that we could choose in the Dictionary pulldown menu.
