I share Jamesy's frustration. I'm also a designer working with colleagues that have access to my computer, and relied on this option to automatically log me out when I quit Evernote at the end of each day. And yes, ScottLougheed's suggestion about setting up a separate password protected user account is something I know I should probably do. I could also add the extra step of manually logging out befire I quit the program. But that's not the point, this feature aleady existed (at least in my Mac App Store version), and removing it seems completely unneccesary. Please bring it back!
