It works like a charm Copy, paste and cut text on PDFs in the document editor. " At first I thought they were scammers, but I took the risk and paid for what they asked for. Now I use almost everything they offer. I like that I do not need to download and upload the document back. I would like to print the document immediately after editing. Now I need to save it first and then I can print the document

A good pdf editor, although there is still some work to do with the command consistency with the environment (windows keys, for instance while editing a document if we press home the screen goes to the header of the document).
