GI has published an article about the user menu system in Skyrim.
It seems like it is mainly designed for console players and takes up some actual ideas from other interfaces. Right now I wonder how they will make this good for PC gamers?
There's an ongoing discussion about this and the update in http://www.gamesas.com/index.php?/topic/1162902-gi-hub-update-ui-2/page__st__80. Please use that.
