This Feature is one of the simplest to implement and its one of the most useful when implemented.
This is simply two indicators which would be added to the nose gear camera on each commercial plane in the game which would aid when turning during taxi. What you would basically do is keep the dot on the taxi way line when turning. This would keep your turn as smooth as possible and it would be more conveniant then switching cameras again and again. Its a really small feature which would help alot in the long term.
Note: this is my first feature request so pm me if ive done anything wrong.
