   Configure application settings in `main()`, before you call `app.start()` on the application object. If you change display settings during runtime, for example in `simpleInitApp()`, you must call `app.restart()` to make them take effect.

  -WARNING: The settings are saved based on the title of your game. This means that if you just remove the method call, instead of changing the setting back to the default and running the project again, your settings changes will remain in effect for all projects using that title.
   
   *Note:* Other runtime settings are covered in <<jme3/intermediate/simpleapplication#,SimpleApplication>>.
   
  
positive.code: ----
  
  Set the boolean in the AppSettings contructor to true if you want to keep the default settings for values that you do not specify. Set this parameter to false if you want the application to load user settings from previous launches. In either case you can still customize individual settings.
  
  This example toggles the settings to fullscreen while the game is already running. Then it restarts the game context (not the whole game) which applies the changed settings.
