It adds some very useful stuff to the UI, such as 'Read/Unread' markers for books, organizing the quick-select menu and even a mod controller that lets you change the settings on compatible mods without leaving the game. Even if you use a Gamepad/Controller, this is still highly recommended.Skyrim's UI was obviously designed with consoles in mind this changes the inventory and magic menu to a format that is easier to access using a keyboard and mouse.These mods are practically required for every installation of Skyrim, to the point that we believe that Bethesda should simply package these mods along with new copies of the game.
