The player (captain) should talk to the crew more, in my opinion. It could be after an interaction with another ship or they could say something when an event happens!
It could be to focus on a specific quest or to give priase for a certian job. I was also thinking they could comment after I crash into a roid at 50m/s yelling at my driving skill or the resulting damage (it feels weird that they are unbothered by a reactor leak).
It could also be at the station where you task them to get info on potential POIs or to gain knowledge of certian stations or moons.
