HI Lisa,
> The problem is that we lose a large number of use cases, such as picking up the tablet and everything is now gone. It wasn't a step in the process , it was a mistake, Now I want to go back.
I'm not clear how that was covered before?
Either you can go back to a step (probably needs to be 'any' step in the SC text to answer Jason's query), or you can't.
I'm not clear how a web-page would enable you to go back, except to allow people to press back or provide links back to previous steps, which is what this covers.
