Switches the language in the backend directly, without having to leave the opened page!
This administration module can change the set language within seconds in the backend. The module creates a drop-down list, in which all available languages are listed. By clicking, the selected language is loaded and you can continue working on the same page. This is very useful when testing language files or if you want to create screenshots of different languages.
* Changes the language quickly and directly in the backend
