If you have installed many hacks for phpBB (or even if you haven't), the navigation in the admin control panel can seem a bit long.
This hack "closes" all modules and the admin can "open" each one seperately by clicking on the title of that module.
The status of opened/closed modules will be saved in the database for each user with control panel permissions to remember the settings for next time.
It uses a cache system to increase the performance of ACP navigation.
The download contains instructions for those that are with or without the Admin Panel for Junior Admins and Mods hack
