save - prev - next - finish
An ordinary activity form currently has "Save", and "Next >>" buttons.
A wizard form has "Save", "<< Back", "Next >>" and "Finish".
It's confusing that "Next >>" is totally harmless at wizards yet causes irreversible action at ordinary forms. Such design provokes nasty mistakes described here.
Please make the dialog-ending button the same in both scenarios. It may be "Finish" or e.g. "Done" - whatever, one can always customize the label. The point is that it should be the same because it means the same: the task is fulfilled.
