Suggestions are always accepted! I actually just updated the mod to (almost) its former glory. No bobs or shinybobs compatibility yet, as they have not updated to 0.15. BUT! Config options are available once again for many things via the new in-game mod settings, including balance tweaks, tech tree, and individual machine toggles.
Now as for your suggestion.. I'll have to take a look at that mod, I have not heard of it.
EDIT: Just checked it out, very.. interesting. A Factorissimo clone, that you can select to spawn a pipe in the outside world. Hmm... I'm not sure that I can use anything from it.
Maybe I'm not entirely clear on the suggestion, but if it's for the mini refineries (their output) in vanilla, you can output directly to an underground pipe in the center output, and use regular pipe for the other two outputs to avoid mixing fluids.
The flow control mod already has some good custom pipes, including straight and elbow pipes, which can only connect in specific locations. I don't think I need to add anything pipe-specific for this mod, when that mod already exists.
