title: Setting a button permanently enabled
body: <p>I have a list of different buttons named stage1 to stage10. then the stage1 button is the only button that is enabled and the rest are disabled. after the user finished all the questions inside stage1, it will unlock stage2. How can I permanently set a button enabled so that every time the user exits the application and re open it, the button that is set enabled should still be enabled.</p>
