Adding a Vertical/Horizontal Mirror would be cool.

I think it would be great if there was a way to easily mirror your ship either vertically or horizontally.  It gets kind of annoying designing the entire ship by making sure that after every piece I have to make sure I place an opposite one exactly mirrored in order to not mess with the physics of the ship. I realize this may mess up with logic pieces and button inputs, but it would still be helpful.

Possible fix for button input issue:

Make it so that more common inputs are reversed (A -> D, W -> S and vice versa). Maybe make some input flips exclusive to which mirror is done?

For the logic piece issue, I can only really think of a similar thing, but for players like me, I use random keys for my logic so that I can still have some manual inputs and not mess with the automatic ones.

Also a brief description of what weapon types to what would be cool (such as bio vs flame types or what lasers vs rockets are more effective at).
