I am working on a new plugin and I really need help with it as I have not really learnt how to use configs well. Basically this plugin is a way to default names of items through a config if you can help please add me on skype giuseppe42121
If I understand correctly, what you want to accomplish could be pretty difficult. Are you saying that you want to change the name of every ItemStack in the game to a String defined in the config? As for using the config, you can use getConfig().get() or any similar methods (.getString(), .getBoolean(), etc.) to get a value from a key, and set values of keys with getConfig().set(). This is all covered in the JavaDocs and even has its own wiki page, so you obviously did not do your research.
