I just spent a bit of time looking into his mod(s) and they look awesome!
It's not that I don't want to because I love the idea but I think he needs to inject the grid into my wagons.
Either that or he needs to reach out and let me know how to utilize the grid system :)
Currently I don't have time to look into it myself I'm afraid since I recently had a daughter :)
If nothing happens in the short term I will look into it when I have more time ^^
