I like it - it looks really nice. I liked okular as well, but reluctant
to use as the comments and notes were for me locked into okular, which I
did not like. So with this script, I can at least extract them to be
readable from org.

1) Are you planning to also include the edits (new text, ...) into the
org file, as it would be useful to have all those in it.

2) Would it be possible to re-use an existing okular instance? it is a
little bit annoying to have several instances open, when browsing
through notes.

As I said, I like the script, and I am thinking about running this as a
batch job each time I start emacs.

Now we just need the opposite: click in a pdf at a certain location and
org opens with the link to there to add the note - am I dreaming here?

Cheers,

Rainer
