Lack of any de-bouncing mechanism on the Save button in the Create User with Email and Password modal view, which can cause multiple triggers of user creation on Firebase if the user repeatedly taps on the button.

The activity indicator appears too late and it does not really block the user interaction with the Save button.

Ideally, the Save button should not be available for clicking until the previous operation has been completed.
