Add a lock/passcode!

Good app, will likely look to use long-term for business/privacy purposes. What would REALLY sell me on it - and cause me to highly recommend to my colleagues - is if this app had a passcode lock on it. Security and privacy are of the utmost importance in my business and Id love to have a second layer of security on this app built-in.
