I enjoyed the routing part. Bit of a head scratcher at points - trying to position those resistors where they wouldn't be in the way on the top of the board. Fingers crossed I got it right. 
I have to say, the guys over at Fritzing have been incredible in sorting this out. Amazing support, for which they have no idea how grateful I am. I really didn't want to start again on this.
@UltraMagnus, I'm hoping it's supposed to be mirrored for the manufacture. Guess I'll find out one way or another.
