<h3>Advanced usage</h3>
<p>Looking at the source of the debug-bar-extender.php you will notice that there are various filters to control the default settings. This is useful when you are working on a multisite install and want to use the debug bar without having to adjust the settings every time. Here’s an example of how settings enforced by a php file in mu-plugins/ could look like</p>
<pre><code>add_filter( 'debugbarextender_default_settings', 'my_debug_bar_extender_settings' );
// enforce debug bar settings
function my_debug_bar_extender_settings( $default_settings ) {
    $default_settings = array(
            'enable_profiler'               => 1,
            'enable_variable_lookup'        => 1,
            'track_default_vars'            => 0,
            'add_default_checkpoints'       => 1,
            'savequeries_debugmode_enable'  => 1,
            'use_error_log'                 => 0,
            'allow_url_settings'            => 1,
            'enable_admin_bar_menu'         => 1,
    );
    return $default_settings;
}

add_filter( 'debugbarextender_default_checkpoint_actions', 'my_debug_bar_extender_checkpoints' );
// initiate some default checkpoints
function my_debug_bar_extender_checkpoints( $default_checkpoints ) {
    $default_checkpoints = array(
                    'muplugins_loaded',
                    'wp_head',
                    'wp_footer',
                    'loop_start',
                    'loop_end',
                    'shutdown',
    );
    return $default_checkpoints;
}
