What the mod does not change in Tiny Item Animations

The effect is drawn on top of the normal inventory and changes nothing underneath it. No items, blocks, recipes, entities or commands are added, no inventory rules are altered, and stack sizes, click behaviour and shift-clicking all work exactly as they did before.

Everything happens while the screen is being drawn, so nothing is written to the world and nothing is stored in a save. The mod can be added to an existing world or removed from one again with no trace left behind and no risk to the items already in storage.

It is also purely a visual layer on the player's own screen, so it has no effect on what anyone else sees.
