Modules, landing gear, docking computer
Modules : I'm pretty sure ED have a bunch of modules for our ships in mind but it is, to me and my friends, important to have a large choice of these spaceship's upgrades. I'm not necessary talking about useful ones. It could be a module to be able to polarize lenses ("surface of the sun" music playing), another one to activate cockpit armed shutters to resist to extreme heat and so on ...
Landing gears : Docking at stations is fine but landing lacks of immersion. You presently don't feel the "shock" of the landing gears when you hit the ground.
Docking Computer : I like you Mr D.Braben and the 2001 space odissey too

Well, variants of Docking Computer are needed. Still presently when we arrive by station directly from the jump, we cannot see which side the entrance of the station is. It could be usefull to add this feature to the "Docking Computer II". It could bring from the hud an holo landing tunnel or as the 84' Elite, put a road of some strong blinking green lights.
Last, but not least : Players are always looking for something to upgrade when they are playing a character, piloting a car or a spaceship. I could spend myself credits to upgrade for a better Ship front Light module if I had to mine an asteroid from the dark side ... give us a ton of modules and upgrades.
