For security purposes on the Mobile Beta, you should automatically log the user out of ProtonMail completely if the user closes the window. On my Samsung Galaxy SIII, if I close the window and go work on something else, and later press the ProtonMail logo , it brings me right into my Mailbox with having to login at all. That isn't secure and could be assessed while it's open but not being viewed.
My personal banking software, on either a laptop or phone, automatically closes if the user leaves the window for any reason for security purposes.
I think it's a great idea for such a secure service.
