i got an idea,how about larger thrusters
and another one that i think is interesting is...like an thruster that uses an extremely powerful blast that launches the ship at an certain direction,like an emergency strafe thruster so you can dodge an killing blow or a critical hit,but the catch is that you can only use it once,but you can use it again if you repair the ship since the blast is so powerful that it exausts and damages the thruster severly.
but no colateral damage,just the thruster is damaged once active.
you can scrap the idea if you want but it would be good to have that.
