Rumors are that there is a very advanced search technology inside of HyperCard :-D. Remember, you could to full-text searches in your stacks at an amazing speed for the technology at this time?
Then there were plans to integrate a color-HyperCard into QuickTime (i think it was QuickTime 3.0), which would be the flash-killer today. I once implemented a windowing-interface complete with mouse-triple-click handlers and drag and drop, all in HyperTalk.
Awesome. Sad. Good Bye HyperCard.
