Instantly Interact Internally

This mod allows most non-decorative items and blocks to be interacted with directly from inventories and other GUIs, without needing to place or hold them.

For example, you can interact with a Shulker Box item in your inventory to instantly open its container GUI, then interact with a splash healing potion inside that GUI to throw it immediately.

Main Features

The mod provides a hotkey (default: SHIFT + Right Click) for quick interactions, enabling instant use of items in any GUI.

To illustrate, here are representative use cases:

Blocks:

For interactive blocks such as Note Blocks and Bells, their item forms can be interacted with directly in the inventory to play sounds, without placing them in the world.
For GUI blocks such as Crafting Tables, Smithing Tables, Anvils, and Enchanting Tables, quick interaction opens their respective GUIs.
For container blocks such as Barrels, Dispensers, Furnaces, and Shulker Boxes, quick interaction opens their container GUI and allows normal usage. For example, you can open a Barrel in your inventory and use it as extra storage. Items stored remain when the block is placed, but are lost when broken (except for Shulker Boxes).
For processing blocks such as Furnaces, Blast Furnaces, and Brewing Stands, quick interaction allows normal processing. For example, inserting materials into a Furnace from your inventory continues smelting even after the GUI is closed.
These features are not hardcoded to specific blocks — other mods’ blocks with standard implementations will also work.
Container items with unique states (e.g., Barrels storing different contents) cannot stack due to NBT data, unless emptied.

Items:

For functional right-click items such as Ender Eyes, Snowballs, Goat Horns, and Fishing Rods, quick interaction in a GUI uses them without needing to equip them.
Food and potions can also be consumed directly from a GUI. (Note: consumption delays are not yet synced to quick interactions.)

Other Notes

Some modded blocks or items use unique implementations. This mod will only add compatibility where necessary.
An API is provided for other mods or modpacks to extend or customize functionality.
