Extremely useful. In Joomla 2.5 a nasty little piece of code renders the backend almost unusable if you have more than 20 scripts. But the solution is not too hard to find (replace line 28 in admin.jumi.php by $option = JRequest::getCmd('option');)
Wow! a life saver, a great piece of work, brilliant! Usually when you stumble upon a good extension there is always a catch... not this time. From A to Z a truly nice component, my only regret was that I did not find it sooner.
