 
                Allows players to toggle automatic selling of specific items using a customizable GUI
RockAutoSell fits any type of server where auto-selling is useful, including:
When a player breaks a block, the plugin checks if any item in their inventory can be sold. If so, it's instantly sold and money is given. A cooldown (customizable) prevents it from happening too quickly.
