Feature request - Show a confirmation dialog before signing user out

Currently when a user taps on their username in the menu, they are signed out immediately. It is not clear that tapping this name performs this action and it is frustrating to sign back in if you accidentally tap it. Providing a confirmation dialog prior to actually signing the user out would prevent this accidental behavior.
