What do you like best?
It is 100% easier than anything else I have ever used to manipulate and work within pdf files. Please contact me if you would like a reference. I have told everyone about it and how great the site is for true productivity.
What do you dislike?
It is a very robust platform that could use a few more page editing tools - what about cut and paste to move a line of text left or right?
