One of the biggest problems with PDF for Linux is lack of pdf comments support. mean I can't make comments, save them in pdf and sent in to another person. I know that poppler is rendering library, but want to ask you, if it's possible to add comments functionality to open and save comments in PDF files.
Define "comments", do you mean annotations? Because poppler does support adding annotations.
Yes. I mean annotation. I'm using okular and in all the searches about annotations in okular there is a conclusion, that they lack of annotations saving in poppler. This is not a case now. Sorry for disturbing you. P.S. Found the bug in okular, this is my fault, that I haven't read it earlier. https://bugs.kde.org/show_bug.cgi?id=151614
