Adds pipes with restricted connections to easily build parallel pipelines. Includes valves from the Valves mod.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Things related to oil and other fluids.
A crossover pipe would be a great addition to this mod. I'd like to avoid placing an underground pipe for only one tile.
A crossover pipe would be a single tile and allow fluid A to go east<>west and fluid B to go north<>south without mixing.
So basically like this
A╣... ...║...B ═╬═╧ ...║... ...║...
Would be useful yea, but undergrounds shouldn't be left in the dark entirely. I'd still +1 this suggestion.
