Recently, my external key switch broke, so now it is either always on or always off. I was looking to see if there was a mod that could be programmed to where you can have one button that starts the engine, but doesn't stop it, then another button that stops the engine, and nothing else, when I stumbled upon this thread. Diamondback said that a multiple stage igniton system would be incredibly difficult to implement due to mod compatibility and UI and all, but I was wondering if it would be hard to implement a feature that allows the player to have one button that starts the engine, but doesn't stop it, then another button that stops the engine, and nothing else.
