Just build it into your theme using CSS and maybe some javascript. Most modern themes should support it without any problems. Might not even have to change the theme’s php files just the CSS depending on what browsers you want to support.
Open adminmenu.css.php and find these lines:
/*
$fluency = ($_GET['fluency'] == 1) ? true : false;
$mu = ($_GET['mu'] == 1) ? true : false;
*/
Replace with:
@$fluency = ($_GET['fluency'] == 1) ? true : false;
@$mu = ($_GET['mu'] == 1) ? true : false;
Has to do with your PHP error settings. Without these defined, it will throw warning notices and cause PHP to stop operation. The @ will suppress any errors if you don’t have Fluency or Mu installed.
