With this update you can now switch between the language English, German and Custom.
To Change the Language, go to the "config.yml" in the "plugins/Ore-Control" folder an set the value "language" to english, german/deutsch or custom.
After this start / restart the server or execute the command "/orecontrol reload".

You find the Language files in the "plugins/Ore-Control/lang" folder. The custom language file is the "messages.yml" in the "plugins/Ore-Control" folder.

I also add an info ItemStack to the Gui, this ItemStack display you which ore / setting / world / biome you currently edit.
