I would like a tool to highlight text and write text box comments in PDFs I review.
Xournal is the best option currently.
I also tried KDE Okular, PDFedit, ghostview and Gnome Evince 2.26. None of these have the annotation capabilities I need.(Evince 2.28 might get them, but Ubuntu 9.10 is needed to install it). PDFedit did have a nice way to move text comments, which Xournal is missing, but highlighting and page flipping is not working for me.
