It would be nice to filter notes and to only download requested. Several filter options come to my mind:
by user (exclude + only mentioned)
by status
I often want to get rid of closed owns as the system gets quite slow with lots of notes.
by time (span of time, creation + closed)
Maybe even a combination would be cool in order to find only the notes closed by a certain user in a specific timespan.
