Is this PrintPDF thing something that could be run (or ported to run) on the DR itself?
If the main functionality can be, I think it could be extremely useful (for me, that is) if it could be merged with the main UI so annotated PDFs can be generated right away from PDFs + annotations. I think it shouldn't be too hard to implement something along the lines of:
Select PDF -> Open with, or some other menu -> Small dialog draft:
[x] Generate <myfile>_notesonly.pdf
[x] Generate <myfile>_annotated.pdf
[x] Delete exported annotations from DB.
What do you think?
