I constantly switch between Windows and Ubuntu and I usually add comments and/or bookmarks in my PDF documents. Now I'm using Adobe PDF and Okular, but the bookmarks, comments and highlighting are not compatible at all, so I only can use them in one of them, having to change the system everytime I need to add something when I'm in Ubuntu.
Okular apparently is in Windows too, but I haven't seen anything more than a mention in the official page. Some ideas? Thank you so much.
