When you copy the settings of a machine and paste to another, the modules from the source machine will also be pasted. If there are not enough modules in your inventory, they will be delivered by construction robots. Useful if you want to combine different modules in the same machine where quick insert cannot simply achieve, like 3x Efficiency 3 + 1x Speed 3. In addition, this mod makes mining drills, furnaces, labs and beacons copy-and-pastable.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
