I wasn't sure what all this would do, but I LOVE it! It's nice to be able to scan a document in and change it without having to re-do the whole thing! YAY!

It runs smoothly and quickly. It appears to have every feature I need in my daily work with PDF files, except one. It would be a fully completed utility if it included options for arranging/rearranging pages in PDF files. If it has that feature I am unable to find it. With this feature I'd rate it 5 stars.

I like it, but I do want to use the same form and just change a name and date of birth for a sibling. Can I do that or do I have to fill out the same form all over again?

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.
