It would be great to add an option to allow the end user to duplicate fields and it automatically generates sequential numbers in the form label (i.e. Form Label Text + {1,2,3,4,5,6, etc.}).
Example:
If an end user is filling out a form for refilling their medication(s), you could just have one text box that has a plus sign icon (floating to the right of the field) and then the end user can click on the plus sign and it will automatically add a text field below with the form fields label + the number of the duplicated form field.
