Firstly, thank you so much for this mod. I love it so much.
I'm not going to call it a bug since it's not 100% necessary, but I do a lot of mirrored blueprints for symmetry in tight places and manifold pumps in a blueprint allow for rotation but not flipping. Not a big deal most of the time, but I've got a very tight nuke power plant in a Factorissimo2 factory with tons of your gold-plated wonder pumps, and I keep messing up with rewiring them and setting balancing logic when I make changes. So the bug is my ineptitude and the suggestion is to foolproof against the likes of me.
