The lack of symmetry was done on purpose. It was intentionally designed to have a one way back, which allows for a world of possibilities, so one would be lead to believe that it will remain that way. But we shall see ...

Yes I thought of that but to order them all correctly oriented for whatever you are doing would suck. Maybe it would be nice but I'm having a hard time thinking of a practical anytime use for it. It's also somewhat tough to spot quickly. If you think of anything however, I'd love to know.
