I want to annotate a pdf in Xournal while at the same time having another Xournal document open to make some calculations. Is that possible?
(Problem: if I open a pdf document on Xournal to annotate it and then click on "File -> New" the annotated document disappears (is closed?) and I have to open it anew.)
Details: Ubuntu 13.10, Unity, Xournal 0.4.7
