I would be really handy know how many engines are needed to move a planet you've placed in a system. so far the only way i know how to find out is to play the system and see.
If I remember correctly, planets with a size less than 300 require 3 engines. Would be a nice UI update. I'll add it to the GUI discussion.
I haven't even touched the system editor yet. I've just started an entirely new section in the GUI list. https://docs.google.com/document/d/1Ef3DmBUsW3faaoqqmhZFgZsyO5JUXSETY5JmXLFIPlQ/edit?usp=sharing
