Patternium

Patternium lets a player place a whole crafting grid arrangement at once, with items split evenly across grid slots. A 2×2 recipe for 64 oak planks, for example, can be laid out with 16 planks in each slot. Overflow dropping fills whatever inventory space is left and picks up the output, so a full inventory does not stall a batch. Holding Ctrl and Shift while clicking runs the bulk action, and shift-clicking the result works as it does in vanilla.

The mod works on vanilla, Fabric, Paper and Spigot servers that allow vanilla clients. It simulates ordinary inventory clicks through clickSlot in ClientPlayerInteractionManager, so the server sees the same clicks a player would produce by hand and no special packets change the world state on the server side. Some servers ban inventory modification and macro mods, so the server rules should be read first.
