Think your list is comprehensive, or is it just an off-the-cuff summary? I mean, the full list must be a pretty good start to making actually decent notes-software.
Off-the-cuff; there are certainly more categories.
Notes related behavior is a good place to find ideas, but not a good goal itself. 'Notes' is where information lands which isn't being specifically captured. Looking at your organization's notes will draw the outline of the system which isn't present, what feature the present system is missing, or what training doesn't cover.
I always have a dumping ground of uncategorized piecemeal notes in whatever note-taker I'm using at the time which I usually call the 'heap' (like a heap of dirty laundry)
