Re: Data's station switch
From a production point of view, putting Data on the port side of the bridge, put him on the same side as the two turbo lifts, and the door to the ready room. After the first season the helm was largely occupied by a dialog-less extra (and Wesley), who sat next to the unused door to the emergency turbo lift.
In terms of camera angles, moving Data made a lot of sense.
Just because it's futuristic doesn't mean it's practical.
