The thruster has 4 spots that you can put a small item on each one of those spots for storage (I'm assuming). It would be nice if when you attach say: a battery, small solar panel, small wind turbine to those spots and attach it to the back of your larger vehicle (and possibly anything else the thruster may attach to, I'm not that far in the game I don't know if it does yet) that it would charge your car from where it sits on the thruster. The design of this game is so intelligent that when I did it I assumed it would work and was surprised that is didn't. So I just thought It'd be nice to see it as a functional feature. I just think it would speak for the already intelligent design of the game. Also I hate that I cant just put single Items anywhere I want on the the open ports on the back of the ship. It autofills you from the seat on back.
