Adds stack inserters for when you aren't playing with Space Age enabled. Still requires Space Age expansion to have been purchased.
Mods introducing new content into the game.
Would be nice to have stack unlock a little more early, yellow science is very late for no space age run.

That makes sense, but I would move the original from chemical to productivity, as that is when material use first REALLY picks up.
