This Plugin replaces the Original WPML Lanuage Switcher in your backend with a brand new one perfectly placed in the Admin Bar! 
It does not touch your frontend language switcher or anything else in your WPML installation.
See the screenshots section, to see the exact changes that will be made.
If you like the new addition, please rate the plugin good. And tell the WPML developers, that we need this implemented in the core of WPML. 😉
