I feel the tadpole should have a HUD displaying at the very least an artificial horizon. Without feeling gravity (in-game gravity that is) it is practically unavoidable to become spatially disoriented to some extent. Having at the very minimum an artificial horizon would greatly alleviate that problem.
If one wanted to be fancy, one might add a slip indicator the way fighter jets use them: A little line with a circle at the end originating in the visual center, showing a slip vector, i.e. if the craft is currently moving up, down or sideways without changing its heading. Given that the tadpole can in fact strafe in any direction, that feature would also help the player understand the movement of his or her craft better.
