To reduce some time used to input data on various places that requires numbers (ex: fuel tank width, translate parts, rotate parts, etc…), i suggest allowing operator inputs such as addition, subtraction, multiplication, division ( + , - , * , / , ) to first evaluate then use the output as the actual value.
Sample use case:
I want a a fuel tank to be exactly 1/3 of whatever my rocket’s nose cone length would be, but i cannot decide the length of my nose cone. Instead of bringing out a calculator in real life, typing into calc, eval, and typing back again into the game, which can take a lot of time if i cannot decide on a length i desired, i can just use ctrl + c, paste to fuel tank length, add “ / 3” and voila the fuel tank is now exactly 1/3 of whatever my nose cone at a fraction of the time.
