This mod allows you to open happy ghast's inventory GUI making it easy to equip/unequip any harnesses at any point without the requirement for shears!
Same way as to how vanilla mount inventories work; Simply press your inventory key while on the happy ghast (Default [E]). This allows you to place any other harnesses on the happy ghast without closing the GUI.


You can easily toggle back to using your regular inventory at any time by pressing [H] (Configurable).
The mod works completely client-sided, not needing authority on multiplayer servers and should work on any server regardless of restrictive procedures.
