Nope. I don't think it was me vaderios, as I remember Ady mentioning that he was actually planning to keep the 'elevator' window look. Sounds great if he can manage that. However, there's another, totally different 'open' SE window that has been restored to it's former, original look to resolve a 'continuity' problem. (there's a comparison shot of it amongst Adywan's preview shots on page 1 of this thread)
But I liked your mock-up of this one too. :)
