From HyperTIES, into this reader:

• Mandatory per-article definition — Definition previews
• Single click reads, double click goes
• Click the background, Reveal all links
• Pop-out highlight with drop-shadow — motion as the cheapest "this is live" signal
• Dimmed-but-enabled instead of disabled
• One markup language for content and shared definitions
• Authorability chosen over SGML
• Storyboards compiled and dumped as an image — The stack
• Scriptable embedded applets
• Pie menus for link routing — Self revealing
• Browse and edit as a toggle, not two programs
• Controlled experiments before defaults — The blue link, Lift-off

The Story of HyperTIES is the hub. The Medium wall is the raw source. XanaTIES is the name that rings. Then HyperCard → HyperLook.
