when walking down the queue inside the actual building of space mountain i notice all the backlit pictures of galaxies and stars.
they're static and very 2 dimensional. True we don't spend much time actually looking at them but it would be maybe a nice detail to make it look like it has a bit more depth.
i dont know how much room is behind the faux windows but i think it would be cool if they could remove the pictures and then install an omni projector behind where the static pictures used to be.
by using an omni projector the people walking towards it would see the same image through the 3 panes. the ones that im talking about specifically are at 1:20 in this video.

By doing that it could display twinkling stars a galaxy slowly rotating in the far far distance and other ships arriving or departing the station.
also at 1:13 in the video theres the map of the space station. maybe an LCD screen could be installed behind plexiglass and have a transparent touch pad overlay over it so you can interact with it. it can point out your current location or display space departure times rotate the model to see the other ports on the space station, stuff like that.
these ideas are all based on the assumption of course that space mountain is one of these things:
