The Unity Desktop Shell for GNOME 3 on Ubuntu Linux has created a lot of controversy in the desktop Linux world. Some users love the new forward looking vision of Unity while others long for a more traditional desktop layout. One of the criticisms of Unity has been its lack of configuration settings. While many configuration settings have been added to Unity since the initial release, most of them remain hidden from regular users. That's where the Unity Tweak Tool comes in. It provides GUI access to many of Unity's hidden settings and collects them together under one convenient application.
