ItemSwap

Usage

In the inventory screen, hold the configuration key (L by default) while hovering a slot, drag your cursor to another slot and release the configuration key. If both slots are valid, you've successfully created a mapping. A mapping allows you to shift-click items between those 2 slots, rather than sending the item to the first available slot in the inventory/hotbar. Creating a new mapping on slots that are already used by other mappings will remove the existing mappings. There's also a keybind to reset all mappings, that you have to tap twice within 500ms (configurable).

Configuring

Execute /itemswap config or use Mod Menu.
