So many great changes I'm looking forward to using in the new update! Being able to flip oil refineries and chemical plants is a huge QoL upgrade for making compact, tileable designs. If I need to scale a refinery/chemical pipeline hotizontally, I can just copy it, flip it, and butt the inputs or outputs together.
Setting assembler recipes with the circuit network seems more powerful (and complicated, seen by the number of combinators) than most players will ever use, but that's why I love this game. I think it's really funny how the devs went from, "Parametized blueprints might be too complicated for players," to, "just build a finite state machine out of logic gates to control your assembly machines." I'm really looking forward to seeing what other people are capable of doing with this. I'll have to dust off my notes from my digital logic classes before I have a go at it.
P.S. The devs totally missed the chance to make a Missy Elliott reference: "I put my thing down, flip it and reverse it."
