Why editing PDF text matters in PDF workflows

when I cancelled a duplicate purchase my account showed that I had expired but within just a few minutes the email was answered and I was on the road to using this product. very happy

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.
Rob
I was a little confused but looks like it will be great once I have the time to sit down and go through a tutorial and then set up my "forms"
Michelle A
This system is amazing, but I have trouble with the 40 per month fee, but I will notify my supervisors at the business, it would be a great investment for the company as a whole.
Eric S
