Hi @conronro :) Thank you, it's a really nice idea! Already in our roadmap. We call it memcopy (it means copy memory which contains program from one craftomate to another).
Mushrooms is some kind of legacy from the previous versions of the game. Previously the game's goal was to create enough oxygen, water and food (mushrooms) to make the planet ready for humans living. It will be changed in the upcoming updates :)
