I am looking to accomplish the following on my list form. New Item would have 3 buttons, like saveDraft, submit and cancel. When the form is submitted it will be viewable by all users but if a user just saves as draft it is only viewable to the person submitting the form?
I would instead recommend putting a simple Yes / No check box on your form. Default it to Yes (checked) and that column would be called "Save as draft?". Adding an actual button control at the bottom of the form isn't impossible but, a lot of extra work when it can just as easily be accomplished via a check box.
