As far as I can tell there are approximately four items of metadata associated with each note: title, assigned date, parent project, and whether or not it’s on the agenda.
I’m wondering if in the future it might be possible to associate additional metadata parameters with notes? For example, date/time of note creation and date/time of most-recent date modification. Also, it can be useful to associate a tag with an entire note, as opposed to inserting one in-line. (for example, one might wish to tag a particular note as #grocery-list and then individual items within as #fruits or #vegetables)
