Xournal is excellent. Here's one small thing that might make it even better: When I enter text, then export to pdf, then display that file in another pdf display program, and try to copy that new text, that text is garbled. It appears to be a 1-1 mapping. E.g.,
If I type 'Rensselaer Polytechnic Institute', than copy it, I get '6IRWWIPEIV 4SP]XIGLRMG -RWXMXYXI'. It's clear that xournal is using some odd font mapping. Is there a way to standardize this?
