An alternate control scheme that gives individual control to each of the engines rather than the turning override system currently in place.
Currently, if you want to turn, the steering wheel overrides whatever speed setting there is on the turning engines and puts one at full forward, the other at full reverse. On ships that have a main engine to provide most of its thrust, this still allows you to move forward/backwards and turn at the same time. However, on ships like the Squid that have no main thrust engine, you cannot thrust forward/backwards while turning at the same time.
To see for yourself, take a Squid, put it at full throttle, and turn hard while watching your map. It spins but goes nowhere.
This affects others ships as well when maintaining speed is of great importance. Having one engine in full reverse for a turn is going to reduce your speed. A better way to turn while maintaining speed would be to reduce thrust on one side rather than completely reversing it.
Arguably, these problems are addressed by turning the steering wheel for only a fraction of a second, but I have no idea if what is seen by the behavior of the engines matches their actual output.
Being able to have more control of the turning engines would allow more fine control over high speed turns, and make it easier to maintain top speed.
As a side note, there should be a speedometer for practice, too.
