PROS: With this software I am now able to do almost anything with a pdf file. For just a few dollars this has been a can't-live-without find! I'm no longer aggravated by filling out long pdf forms and being unable to save my work. I'm able to save, edit or even create new fields in any existing pdf. I can also create my own from scratch including fill-in fields just like the pros! The free tools and writer are an added bonus. I can't say enough good things about this software, I wish I had found it years ago and saved myself some gray hairs. Trust me, if you work with pdf files then the PDFill Editor is worth it's weight in gold. CONS: 1. If you get the trial version it will put a watermark across your document when you print it until/unless you buy the registered version, as you'd expect. 2. Strange as it sounds there is no "undo" feature in the editor (that I've found) so you need to save your work often, especially as you are learning it.
