It is HIGHLY unexpected that cloning a form does not include the defined simple workflow. I missed a couple of lead flows after having cloned a form with a simple workflow.
The dialog actually shows it, but it really is USELESS as I cannot copy the workflow from the original form to the clone.
REQUIREMENT
When a form with a worklow is cloned then the workflow is cloned to the new form as well.
The workflow is disabled by default.
ALTERNATIVE IMPLEMENTATION
Make the simple workflows from the original form be available as a workflow to link to the cloned form.
