I like that my information is saved and I do not have to keep writing over my applications. I can get it quickly when I see a job I want to apply for.

At first was a bit different in look and function but after a short time became very easy and logical to use. Still wish you could print directly from editing screen.

I enjoy updating documents without creating a entirely new document. I wish there was shading an area after you erase to match the background of the document.

Easy to use once I figured it out - with 3 jobs it has become mandatory to use/edit pdf which I have been trying to avoid. Thanks!
Update: Still liking this program!

Very useful! What I most liked is the signature with verified by PDFfiller. There are couple of times I cannot edit properly but this should be how the pdf file was created. For example, to change page number, I wasn't able to do this properly so end up sending my forms as they were.
