RE: What do I use?

Oh dog-poop.

Oh, double dog-poop!

Sequential screens are perfectly valid in just about any application.

There

are times when you need things to be done in a specific order, whether

it's

authorizing a credit card bill or verifying a bank transfer.

I'm not talking about going out of sequence, as in page 1 to page 3,
skipping page 2. I'm talking about doing page 1, then 2, then 3, then
oops, back to 2, then 2 again, then 3. Are there times when you can't
allow that? Sure, but they're really few and far-between. Much rarer
than applications that "prevent" the back button would like.

If I'm authorizing a transaction then if I approve it, then back and
then attempt to approve it again, the app should say, "hey dummy, you
already did that." After all, I might be trying to go back 3 screens to
the list of transactions so I can select the next one to authorize.

It's much simpler to prevent the back button and think linearly, it's
what we've done for years. It's much more web-like to think differently.
