Fill and Sign Good Suggestion!
When you create your Digital Signature thru the Fill and Sign Wizard that say you like how your first name looks but then when you get to your last name and you make a mistake that instead of clicking the Clear Button to start over that you could Click a Button that says Undo instead as this would really save a lot of time in the long run being that it takes quite a while and too long at that to do that if you like it to look just right both ways both first and last name.
