An upgrade to Synth that lets you queue things better would be cool. Like split Synth 1 and 2 from 3 and 4 so I can have 1 and 2 Smart Synthing Circuitry and 3 and 4 Smart Synthing Focusers without 1 and 2 taking all of the Alloy since Circuitry is cheaper and preventing 3 and 4 from ever making any Focusers.
