This free WPML Addon removes the WP Menus Sync sub menu from the WPML sidebar menu in the backend.
You can stop looking, there are no settings. The Addon just works in the background.
This plugin is an Addon for WPML, the plugin that enables any WordPress website to become 100% multilingual. If you don't have WPML installed, this Addon is useless, so better not install it.
