Hi, I'd like an option where Boxcrypt automatically logs off when: (a) there is a period of inactivity, or (b) the screensaver/screen lock is activated (PC). Options like this are available in TrueCrypt and Roboform, for example. Also, and I think more importantly, in the iOS app it would be nice to optionally require a simple 4-digit passcode each time the app is opened in addition to the initial username/password authentication; the Dropbox iOS app has this option.
