It sounds as if you need a stack of stacks, not a stack of cards.  In other
words, you could have a bunch of stacks that belong to a "superstack".  The
background of the superstack should define forward and backward buttons that
allow navigating among the primary cards of each aggregate stack.  The primary
card of each aggregate stack should define additional buttons enabling browsing
through its cards.  You could even put in a fast browse button.  Copy it from
one of the provided stacks if you don't know advanced HyperTalk.

To know how many cards are in a stack, you can define a button in its primary
card that performs a HyperTalk "domenu stack info".  This will bring up the
stack information menu.

Try browsing the provided stacks.  It's likely you'll find a similar
application.  You can copy this and use it as a template for developing your
own.  Have fun.
