A new checkbox has been added to the settings UI to enable/disable this feature.

refactor(SettingManager.py): add default settings dictionary and refactor createInitialSettings method feat(SettingManager.py): add new settings to the config file if they are not present The default_settings dictionary is added to the SettingManager class to store the default values for the settings. The createInitialSettings method is refactored to use the default_settings dictionary to set the initial values of the settings. If new settings are added to the default_settings dictionary, they are added to the config file if they are not already present. The remove_changed method is added to remove the has_changed flag.
