1]Add custom WordPress dashboard logo

Inorder to add a custom logo to your wordpress admin panel use the following code

add_action('login_head', 'my_wordpress_custom_login_logo');
function my_wordpress_custom_logo() {
   echo "<img src='location_to_my_img'>";
}

2]Remove wordpress dashboard widgets

It is not good to show the dashboard widgets like whats happening, blog rolls etc to the users. So to remove that use the following code

add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
function remove_dashboard_widgets() {
 	global $wp_meta_boxes;
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_incoming_links']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_right_now']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);
}

3]Add extra widgets to wordpress dashboard

In some cases we need to have some custom widgets in the wordpress dashboard. We can achieve it by

function custom_dashboard_widget_function() {
	// Display whatever you want to show
	echo "Hello World, I'm a great Dashboard Widget";
} 

// Create the function use in the action hook
function custom_add_dashboard_widgets() {
	wp_add_dashboard_widget('custom_dashboard_widget', 'Custom Dashboard Widget', 'custom_dashboard_widget_function');
}
// Hoook into the 'wp_dashboard_setup' action to register our functions
add_action('wp_dashboard_setup', 'custom_add_dashboard_widgets' );

4]Remove the “Upgrade now” notification

There can be a catastrophic output in some cases when the client upgrades the site. So a better way is to disable the upgrade notification. To disable it

if ( !current_user_can( 'edit_users' ) ) {
  add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
  add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
}

5] Remove default fields from the wordpress profile

In some cases, we need to remove the user profile fileds like bio, aol, jabber etc. Use the following code for that

function profile_admin_buffer_start() { ob_start("remove_plain_bio"); }
function profile_admin_buffer_end() { ob_end_flush(); }
add_action('admin_head', 'profile_admin_buffer_start');
add_action('admin_footer', 'profile_admin_buffer_end');
add_filter('user_contactmethods','hide_profile_fields',10,1);
add_action('admin_head','hide_personal_options');
function remove_plain_bio($buffer) {
	$titles = array('#<h3>About Yourself</h3>#','#<h3>About the user</h3>#');
	$buffer=preg_replace($titles,'<h3>Password</h3>',$buffer,1);
	$biotable='#<h3>Password</h3>.+?<table.+?/tr>#s';
	$buffer=preg_replace($biotable,'<h3>Password</h3> <table>',$buffer,1);
	return $buffer;
}
function hide_profile_fields( $contactmethods ) {
	unset($contactmethods['aim']);
	unset($contactmethods['jabber']);
	unset($contactmethods['yim']);
	unset($contactmethods['url']);
	unset($contactmethods['pre_user_url']);
	return $contactmethods;
}
function hide_personal_options(){
	echo "n" . '<script type="text/javascript">jQuery(document).ready(function($) { $('form#your-profile > h3:first').hide(); $('form#your-profile > table:first').hide(); $('form#your-profile').show(); });</script>' . "n";
}
