+1 for evernote integration.. Flow seems to have much potential..
And not just the basic add a note to notebook x, do that integration, but also add a note with a specific tag, do x or add a note to a notebook that is inside of notebook stack x, do y, etc..
It is the missing connector I need to consider Microsoft Flow as an alternative to Zapier, Tray or even IFTTT (minimal and simpler, but got most basic connectors, like Evernote).
