I have tested it and every elements concerning my line of work are deeply thought out and very crisp.
I had a problem of sending a folder but the solution is in merging the files to create one new file to send.
The software is brilliant and less costly than all the competition I have tested.

In my opinion this application is very powerful, however not so intuitive, and I had to spend an inordinate amount of time in chat with technical support personnel. I would be happy to explain further.

I like the program a lot. You recently changed the format a little. When I want to save a document to my computer, I can't tell it where to save it; it automatically saves it to my downloads, which I do not like. Before you changed the format, I was able to save a PDF completed document to whatever file I needed to on my computer. I would like to be able to do that again.
