Redux Framework, when run as a plugin ships with a sample config in order to permit people to try Redux out without effort. However, if you intend to ship Redux Framework with a premium theme or product, this is less than desirable. You can easily disable these demo items with the following snippet:

function removeDemoModeLink() { // Be sure to rename this function to something more unique
    if ( class_exists('ReduxFrameworkPlugin') ) {
        remove_filter( 'plugin_row_meta', array( ReduxFrameworkPlugin::get_instance(), 'plugin_metalinks'), null, 2 );
    }
    if ( class_exists('ReduxFrameworkPlugin') ) {
        remove_action('admin_notices', array( ReduxFrameworkPlugin::get_instance(), 'admin_notices' ) );    
    }
}
add_action('init', 'removeDemoModeLink');

Place that anywhere in your theme and all demo mode references will be hidden.
