Sugardust A crew alarm that sounds when approaching a contact, maybe some flashing red lights as well?
Good idea, indeed not that hard to implement
Sugardust Various PA system voice lines, which just read off simple tasks to be done or names of crew members to show up to different parts of the ship.
Would be easy to implement IF Walt had a voice-actor at his disposal. And even then, will it be a male voice? A female voice? An alien voice? All three? Good voice-actors are expensive!
YES
Sugardust Crew yelling and sounds of war when zoomed in close to your ship in a battle.
Same problem, would require even more voice-actors or stock sounds. And again; alien or human or both?
Some nice minor things, I think all of these are still good ideas but some of them might not be implemented for another year or two.
