Works okay, looks so very 2012

Really nice app. Good for security, too. Could use a redesign to give it a (optional) more iOS-7 (or even iOS-9; San Francisco typeface, etc.) look. Also, could we secure our Macs using more options than just the pattern unlock? Specifically, 4- or 6-digit passcode. Or even (dare I say it?) Slide to Unlock. Thanks.
