I spent hours working on a PDF form and thought it was perfect. Now that I have been using it, I can see changes I want to make to it. Just clicking the "Edit PDF" tab does not allow me to edit to the degree I want or need. I do not want to completely start over, I just want to get back into the "Create PDF" mode of the doc that I had when I originally created the form so that I can tweek it to be how I need it to be. Is there a way to do that?
