If, after having changed the events database to suit yourself, you then decide to restore it to the same state as it was originally supplied, you can do so in the Rest View.

To prevent you from taking this irreversible step inadvertently, the red "Reset" button is disabled, and needs to be enabled with the "Reset Enable Switch", if you really want to reset all the events, and lose all your changes.

And the "More" button will take you back to the More View.
