While nothing about the UI looks markedly different from long-running MMORPG conventions, there is an interesting hint at a mechanic that is unique to NCsoft's upcoming fantasy martial arts epic. The Qinggong meter (the green bar below the health and fuel meters) ties in to the game's travel system and looks to put a novel spin on both exploration and fast travel. If you're wondering, Qinggong is a Chinese martial art that has been heavily stylized in Wuxia fiction (see the wire-fu action sequences in films like Crouching Tiger, Hidden Dragon, House of Flying Daggers, and The Matrix).
Blade & Soul Dojo also confirms that the game will have an auction house as well as social features including mail, a news page, and a calendar (though these features were disabled in the beta). Check out the original article for more details.
