>For example, right now, moving a file breaks its relationship with a note, and an open file's notes aren't associated with the file's finder icon. That's interesting. Is there a workaround or quick way to transfer notes? I often rearrange files.
There kind of are it just requires a little more work on our end. We will hopefully be able to share that with people soon. Interestingly and anecdotally when moved around in dropbox it seems to keep it's relationship.
However, I’m not sure if you can use these without the user choosing the file with an open panel, or with drag and drop. That’s what I had to rely on with my app Blik: http://www.burntcaramel.com/blik/
Ghostnote looks great, by the way!
