I found this screen by accident, while doing something else (smelting up some ore). I'm guessing that this is the construction interface for crafting smart tubes? But there's nothing to craft, nothing to do. Maybe some time later I'll accidentally stumble across recipes or something that activates the mod; something beyond, you know, installing the mod. I found this screen while playing Frackin' Universe mod, and intending to use the FU mod. Guess what? I made things with the Frackin' Universe mod.
