good program, found it easy to use. I really like the layouts and how user friendly it was. My only concern was the pricing for me, I only needed to use it for a couple of project a month and I found cheaper yearly memberships elsewhere

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.
