what's cool about those private notes?

encrypted replaceable events that ARE NOT linked to your main identity; no one can see meta data and relate it to your main account

anything else? oh well, funny you should ask, you can grant permissions to others to collaborate on that note

and what else? oh, well, it just happens that those notes can tag ANY kind of event, which means you can embed within a text note anything, a song, a user, a file, another list

this client is going to be absolutely insane; everything evernote always dreamed to be but never had a change of achieving
