TotemHelper
A client-side quality-of-life mod that keeps a totem of undying in the slot you chose.

You tell TotemHelper which hotbar slot your totem belongs in. From then on it makes sure a totem actually ends up there — and in your offhand — instead of you dragging it around by hand every time you pick a new one up.

What it does

1. It keeps the totem in your hand when you leave a container. Whenever you open your inventory, a chest, or any other container, the hotbar selector moves to the slot holding your totem. If the totem is in the slot you configured, it goes there; if it is somewhere else in the hotbar, the selector follows it. Close the screen and the totem is in your hand.

1. It puts totems in place when you hover over them. While a container screen is open, move the mouse over a totem of undying and the mod moves it for you:

If your offhand does not hold a totem, it goes there first. That is the slot that actually triggers on death, so it takes priority.
Otherwise, if your configured hotbar slot does not hold a totem, it goes there.
If both already hold a totem, nothing happens.
One totem moves per hover, so picking up a stack of totems from a chest fills the offhand first and the hotbar slot on the next one.

1. It stays out of your way. The mod does nothing while you are carrying an item on the cursor, does nothing when it is switched off, and does nothing outside of container screens.

How it works, in plain terms
TotemHelper does not add items, blocks, or recipes, and it does not change any game rule. It performs ordinary inventory clicks — the exact same swap action you would perform by pressing F over a slot — and sends the same packets the vanilla client sends. Everything happens on your machine.

Things you should know before installing
Moving a totem is a swap, not a copy. If your offhand holds something else — a shield, for example — that item is swapped into the inventory slot the totem came from. Nothing is lost, but the shield does leave your offhand.
This mod automates inventory actions. It clicks for you. Some servers, especially PvP and anarchy servers, consider that unfair automation regardless of the fact that it only uses vanilla packets. Check your server’s rules, and ask staff if you are unsure. Use the on/off toggle when you play somewhere it is not allowed.
It only reacts to totems of undying. No other item is touched.
