Fast Totem Add-on
equip a new totem of undying or shield without opening the inventory for surviving a few more seconds in your world! You only need to right-click or hold the screen and release it with the totem or shield equipped in your main hand.
This add-on provides a more easy way of using undying totems and shields! With just a right-click or interaction, you can quickly and easily move them from your main hand to your off-hand without having to open your inventory. This feature, which is similar to the "F" key option in the Java Edition of the game, makes it much easier to access your totem and stay alive during intense battles. This add-on is also fully compatible with other player.json file-based add-ons, so you don't have to worry about any compatibility issues. Plus, it only requires Beta APIs experiments to be enabled to work, so you can start using it right away. Whether you're fighting in a raid, exploring ancient cities, or having a friendly PvP match with your friends, this complement will enhance your gameplay experience and give you a competitive edge.

The addon now includes a new alert that will fire every time that a player uses an undying totem.

Also this includes a new message like Java achievement: postmortal
