The code of my script is based on that one: The West - Quick items search. I just made a list of all the buffs/products and added multiple languages support.The updated version of that script is linked above.
Searching for specific buffs or products? Easy job using this script. Just some clicks and the items, which you wanted to find, are showed in your inventory.
It adds a button on the right side for showing the different types of buffs and products in the inventory.
Supported languages: English German (Deutsch) Spanish (español) Polish (polski) Italian (italiano) Portuguese (português) French (français) Slovak (slovenčina)
