Well, the way I heard the story is that Martin Gannholm convinced Bill Atkinson
that sharedHilite was possible, and Dan Allen went off and implemented it
according to Martin's design.  It all happened while I was still blissfully
distant from the scene, so I don't really know.

But it's true in any case that Macintosh HyperCard 2.0 borrows several ideas
and some code from HyperCard IIGS.  In particular, the following things were
invented or inspired by Andy and the HyperCard IIGS team.

  - the navigator palette
  - the dontSearch property
  - the fixes to message ordering
  - the extensions to the read and write commands (now in Mac HC 2.1)

And a number of things were designed by the two teams in cooperation.

  - the extensions to the ask and answer commands
  - the create stack command
  - the import and export paint commands
  - the save stack command

So far, HyperCard IIGS doesn't borrow much from Mac HyperCard 2.x -- as far
as I know, just the incredible expanding dialogs.  It looks like HyperCard
IIGS has some catching up to do, in order to become as dependent on us as
we were on them....
