The program is very user friendly. Would like the opportunity to test more documents before sending to clients, so I can see what they are seeing when they receive notification to sign.

This is a very useful program to me in my work. I can easily send documents to be filled in by customers, easy to use and easy to navigate.
I do not have any cons with this program, if you are not utilizing this you should be. It is highly useful and functional

Really like the program.
As mentioned. I use it to update my catalog prices and images for printing.
That it allows me to erase certain parts of my document and insert others. I couldn't figure out how to add my prices to an already made catalog I use.
That I have to come out of the document to look at the completed changes then go back in if it's incorrect.

was able to scan a document and then edit to make current with my next project in terms of headers and body making additions and subtractions to the text as needed

sometimes the app freezes and takes a few minutes to load which can be inconvenient when files are needed quickly. Also some features also drag for example the signature portion. Overall great app which I use daily for my work.
