ToolbarAPI is an API created to help developers set up toolbar menus without having to create complex inventory listeners.

ToolbarAPI can register multiple toolbars at the same time, and players can have different toolbars open at the same time.

Information on how you can use this can be found here: https://github.com/titivermeesch/ToolbarAPI
