Good day, I created a quick mock up of what I wish the controls were like.
Of course the dev team would Steampunkify it however the center info cluster would a instrument panel floating in a glass ball, like a compass or horizon indicator, but with the information presented, ribbon numbers that change, and the left controls work just like the right controls except they control the amount of buoyancy set for the balloon.
if my instrument panel is rejected I would at least like to see forward/backward velocity on the engine control, and upward/downward velocity on the buoyancy balloon control.
Here is a rough picture, but I know the dev team will make it look Gazillion times more awesome. Do you like it?
