I just finished my first run of Sea Block, and I wanted to thank you for creating the Fluid Permutations mod, because I'm pretty sure I would have been driven to madness without it. The ability to change inputs & outputs provides such great flexibility, especially when building in tight spaces (which is most of the time, especially when using beacons). I cannot imagine playing Factorio again without this mod, which is the highest praise I can give.
Thanks for creating such a great mod!
