/dank/null

/dank/null is a mod created by TheRealp455w0rd as a spiritual successor to /dev/null and is also the name of the eponymous item.

Shift right-clicking with the /dank/null in hand will open its GUI. Inserting items into it will automatically store any further copies of items into the /dank/null when picked up, and void any excess once a slot is full. Higher tiers can hold more stacks per slot.

Additionally, alt left-clicking a block in the GUI (or mouse-wheel when in the player's hand) and then right-clicking with the /dank/null will place blocks from its inventory, or build a docking station to automatically drain blocks. Control left-clicking will protect slots from being affected.
