Hi all. I've been tried masterpdfeditor, in the .deb version from official site, and it seems to be quite powerful. Differently from xournal, it allows you to re-edit previous changes to the document, whereas xournal seems not to be able to do that. The problem is, that it is proprietary software that asks for money otherwise more and more `watermarks' are added to the document any time you edit it again. Anyone out there has experimented the matter and found a good solution to the problem of adding some bit of text to pdf documents? In particular, I want to add fingering notation to piano sheet music papers.
Thanks in advance for any help, cheers Rodolfo
