VC state save

[ebswift]

I did an edit on the first post, the state isn't set until the VC is re-opened after it closes. I understand that work can be lost with unexpected termination.

It would be handy for it to do some kind of periodic save without having to close and reopen the VC between steps, it is not a normal way of working with software, many of us are used to working with a save button in cases like this.
