So I've looked at what has been said here. I agree should have it work like the Android app where I can set a pin. Maybe since I'm on Linux, my reason for wanting it a little different. For me the app just stays logged in and just loads up every time I open it. Convenient, yes, but there needs to be a lock for security reasons. I don't even care if it reprompts for the mailbox encryption key.
