// Notes
//      To add a new setting
//      Add the new setting to the session_arg_t; in ui.h
//      Add the default value for the setting in the settings_load page below
//      Update the preferences_load_callback to load your setting into the structure
//      Update the preferences_save_callback to ensure your setting gets saved when needed.
//      use the preference as needed : g_session.<preference name>
//      Can use (g_session.preferences_loaded) to check if json settings file was used
