It works to create bookmarks of a pdf-file. But they are invisible when opened with other programs or sent as mail. In PDFXChangeViewer it is possible to create bookmarks that can be saved like real table of content, visible for anybody reading the file. I'd like to have it in Okular as well. Reproducible: Always Steps to Reproduce: 1. create bookmark 2. safe file 3. open file with other program Actual Results: no bookmarks visible in other program Expected Results: bookmarks visible like table of content Like behavior of PDFXChangeViewer creating permanent bookmarks that can be used as table of content
