We got another shot of that MSD Mike Okuda created for Season 2. But I don't remember when in the episode I saw it, guess I'll have to rewatch the episode, what a shame 

There are multiple windows on Deck 1 on the ship's modelI believe this is the first time where we learned that deck 1 is not always the location of a bridge. The California-class has "penthouse"-type crew quarters on that deck. A single room can house four bunks.
