This has probably already been said, but I think it would be cool have different ships in the ship yard that can be seen from the Ships Requisitions room. Now its the Galaxy and the Excelsior... but it would be nice to see different ones every couple of months. I am pretty sure I've read somewhere a suggestion of having the next new ship to be released in there... but if you don't have the model and textures ready you might not be able to do that.
Would this be hard to do? I think it would be awesome and would give a more lively feeling. To go one step further, a damaged ship or a ship that is clearly under construction would be pretty ridiculous as well.
