Respect Read Only setting specified on a form field
When creating a PDF form, fields can be set to "Read Only" to prevent editing. Fill and Sign PDF Forms does not respect this setting, as those fields are able to be changed in the program. If Read Only fields could be put in the PDF, it would allow giving details about the PDF (e.g. terms and conditions for what the person is signing) without displaying the whole PDF. This would both ensure that the person signing knows the details won't be changed after they sign as well as giving the creator of the PDF confidence that the terms won't be changed before it is signed.
