DeathTPPlus

If you die your inventory is placed in a double chest at the spot you have died, or in the closest available spot, and a headstone (sign) will be erected with your name, time and cause of death. The chest will be filled with as many items as possible. Any excess that won't fit in the chest will be dropped.

You can use the /back command to return to your death location and loot the chest. It will destroy the chest and sign and put everything back into your inventory. It does not autoequip your armor or weapons.
