+1 Really stupid that this is not an option. And I've googled and seen a few threads about this, and see people defending it not being a feature saying thigns like "You can lock your computer". Guess what, you can lock your phone just as easily. There is absolutely no reason this should not be a feature, and it is not something that is complicated to implement. As people have said, this is not something to protect our credit card information from CyberWarfare, its just so that people borrowing my computer wont click in on private notes (with malicious intent or not.) Evernote is all about convinience, that is its only selling point, there is no one function evernote has that is not easily repeatable through other software. And it is very inconvinient for a lot of users that this feature is not implemented.
