Hey guys, this is my first attempt at an Item Editor so don't hate me if there are errors :P
To use just extract your World.dat from your save and load it into the Editor. There is lots of coding do with the Editor so it takes 5-7 seconds to load/save your save.
The Editor can mod your Item ID and the amount of the Item that you have in your stack.
1. Display the Items in the correct combo-box based on the Item position in-game.
2. Add the option to change the Durability of an Item.
3. Fix an errors along the way.
