Guil12

An intelligent crafting machine that searches recipes, builds full recipe trees, calculates materials, and exports crafting plans for complex modpacks.

Automated logistics drones that fly fixed routes between containers to move items for you — five upgradeable tiers, remote-controlled routes, and a charge station to keep them powered.

This mod is perfect for people who like having more slots in Curios API, as it's neither easy nor difficult. And of course, you get extra slots.
