How many cards can you have to a stack?

[Dan Shafer]

Kevin....

There's no theoretical limit on the number of cards a stack can contain 
other than the usual constraint of how much memory your system has. I 
know there are Rev apps out there with tens of thousands of cards.

That said, your question seems to be wanting to find out not the limit 
on cards but how new cards get created and what happens to other cards.

If you have a stack with one card you're using for an "About" screen 
and you want a second card in the same stack to serve another purpose 
(e.g., preferences), you just have to create a new card in the stack, 
which you can do several ways including selecting "New Card" from the 
Object menu. Once you lay out this new card's design, you can switch 
back and forth between the About card and the Preferences card by using 
standard card navigation (go next, go prev, go first, go last, or even 
go to card "About"). The About card probably didn't get deleted, it 
just got hidden when you showed the Preferences card. The opposite will 
also happen.

Now, with all of *that* said, you *probably* want to use multiple 
stacks for this particular situation. For example, your preferences 
card's contents can't be modified and stored at runtime if you create a 
standalone application out of this stack. So there's a whole design 
paradigm you need to think about as well. Rev is really different from 
other app development environments you may know and getting your head 
around these basic concepts is not difficult but it's not simple and 
it's certainly essential.
