Add button on charging screen to ring audible alarm when charging is complete. Needed to alert driver who may be taking a nap or engrossed watching a movie, etc. Add option for alarm volume for loud (nap mode) or low (no need to scare me), or increasing volume until cancel (best). This feature would avoid staying at charger too long, avoid idle fees, free up charging spot, etc. Note, I do not have the Tesla App available when charging, so I don't get app notifications.
