I would love the ability to instantly turn the thrusters off using circuit network control. You can do almost that by using PWM on a fuel pump to control speed; controlling the timer-counter cutoff point is instant, and since the thrusters are already starving at that point, it doesn't take very lo...

I also disagree - it is already possible to throttle ship engines without much trouble (e.g. by PWM'ing the fuel line like how a microcontroller's timer-counter works). I don't think having an even easier option to control the engine thrust would be in the spirit of the game.
