I find that Infix allows me to work with difficult to edit PDFs.
Many government documents including Bankruptcy forms (specifically what I use it for) annoy the heck out of me because I am a perfectionist and like a clean looking document but unfortunately many times the text I type does not align with the pre written text alignment.
I find the use of text boxes in Infix to be a great way to fix it. Even with the option to use floating text boxes to fill forms it also allows the option to use the preexisiting fields to type in answers – traditional style. You can fill in the forms in the way you want want or both on one page, preexisisting fields and or [new] text boxes.
I also like the word processing design and ease to use of Infix.
I would suggest it for any OCD person! LOL
