The lock console feature is a bit of a pain. It requires you to enter the password for the user twice before unlocking the console, as it locks it then sends the user to the login screen. I think it would be best to lock it, and after unlocking, send the user back to where they were before they locked it. Presumably, if the console is locked, it’s because someone doesn’t want someone else (dare I say, even another user) getting on the board and messing with it.
