Well, this is a little pice of must have if you edit a lot in the Joomla Backend. Basickally it lets you jump into articles, modules, plugins, menues whith typing a few letters from the item you are looking for. If you have an article called Download and a menu item with the same name, its no problem, because the instant search result shows weather it is a module, article, plugin. Saves you 2-4 clicks per use!!!
I LOVE IT!!!
