Hi Tim.

This is pretty easy once you get the idea.

In Form options and Open Rules you can set a switch view action to open the
form with a view other than the default.
If you have certain steps of the form typically you would track the steps in
a form state field in the form.
Then on open, you would check the form state and if it = 1 switch to view 1
etc.

Otherwise you could just track the view.  Add a rule to your buttons which
switch the views to also update a field with the view it is being switched
to.  Again then you have data in your form which has the last view used and
you can setup open rules to open to that view.
