We are building an application that has multiple steps. As
each step is completed, I would like it to move off to the left of
the screen with the new screen moving in from the right edge. I am
using multiple states and have created a transition that I would
like to set the targets as the state is changing. The problem is
that the old screen simply disappears, it does not slide away (the
new screen does slide in from the right). Any thoughts?
