Speaking of, oh @Gregorius, have you thought of adding this mod straight in so it has better integration? Though I’d think the UI should be different, maybe a clipboard item, and any clipboards in the inventory (or maybe just hotbar) get the data when you pick up a rock, that way you could have different clipboards for different areas of the world too perhaps, or for different dimensions or so?
Might require a touch of ASM to do outside of GT6, but doesn’t seem hard to do?
A touch of ASM for a callback in the right case would make it pretty trivial. 
Hmm, interesting idea, that could work…
