It would be useful to be able to stop navigation using something like preventDefault or by returning false in listeners to the change event.

A few use cases:

Navigating to another part of the app with unsaved changes
Navigating back to a step when you've gone too far (using manually typed URL or back button)
Navigating to a step (using manually typed URL or forward button) without completing required fields

Good idea! Added this to the latest release!
