customize the admin bar?

I’d love to be able to add/remove menu items to that bar also.

erick_paper,

To edit logo at top left corner:
Requires WordPress to be installed on your own server (not wordpress.com)

• Access the following… /wp-includes/images/admin-bar-sprite.png and open it with your favorite photo editor.
• DO NOT CHANGE THE DIMENSIONS OF THIS FILE! It will mess things up due to the way wordpress uses this image. (Google “CSS Sprites” to learn how it works.)
• Replace the two WordPress “W“s with your desired image. Again, Do not resize the sprite image! Just mask out the Ws and put your logo or whatever in its place. Keep your image in the exact 20px x 20px region the W occupied…
• Be sure to save the .png with transparency (same as original)
• Upload the image you have saved back onto your server and you are done.

As for modding the other stuff on their, I’m workiing on it. Will post here when I get it down.

DerekMX271, modifying core WP files to do some simple tweaking is generally a bad idea (some discussion on the matter here). Any change you do on those files will be overwritten on the next WP update you do. Your tweaks should be done either in functions.php inside your theme files, or with help of a plugin.

To change the amdin logo you can simply create a plugin that loads additional CSS styles, like this :

<?php
/*
Plugin Name: Custom admin styles
Plugin URI: www.mywebsite.com
Description: Custom CSS styles for admin interface.
Author: John Doe
Version: 0.1
Author URI: www.johndoe.com
*/

function add_custom_admin_styles() {
	echo '<style>#header-logo { background-image: url('path/to/my/image.png')!important; }</style>';

}

add_action('admin_head', 'add_custom_admin_styles');

?>

You can then add / modify any styles of the WP admin.
