Definitely tracking note additions in specific notebooks, and/or in general, could be a useful statistic, and Evernote is tied very closely with almost all aspects of my life so it seems like a good fit.
I think this would be number of notes created, and number of notes updated.
If this number is combined with emails processed, and my review, and mostly with time of day, then it could be very useful
If we did add an Evernote integration, it’d be for getting data in, like all other integrations, so this wouldn’t really be possible unfortunately. It’s certainly something you could hook up with our API though.
