I would love the ability to password protect on an app level (I know when can do it on iOS/Android) for Mac and Windows as well as be able to add a password for notes or even entire notebooks.
Bear for Mac allows a password to open the app, then another (different password if you wish) for locked notes. Having that in Evernote would allow me to ditch Bear. It's not a bad app, I just prefer Evernote!
