One copper ingot, not five. Unify duplicate ingots, ores and dusts in your modpack: pick the one to keep from an in-game screen, and tags, recipes and items follow. No scripts, full preview before anything changes.
An assembly table fed by lasers. Fit them with lenses to cut, weld and engrave, run recipes in steps, tune each beam's intensity and keep the table cool. BuildCraft's idea, redesigned, all in datapacks.
Control the large iron and copper ore veins: turn each type off, make veins bigger or smaller, richer or poorer, or rebuild them from any block - even another mod's ore. One config file, no datapack.
A beacon you carry. Pick its effects, choose who they reach, and pay for them in fuel. Four tiers, three themed beacons, fourteen augments, and everything defined in datapacks.
Factorio's inserters, transport belts and assembling machines, in Minecraft. Seven inserters, three belt tiers with ramps, three tiers of crafters, modules, and the Factorio component chain to build them.
Functional Storage drawers for what isn't an item or a fluid: Energy (2 billion FE), Mekanism chemicals and Ars Nouveau Source. Same upgrades, same Storage Controller, framed variants for all.
A dead civilisation ran on energy that never touched a wire. Wake its outposts, learn to read a field you cannot see, and follow it down five tiers to the Rift.
