Drupal Language Switcher menu item I am using D 7.28 with Boostrap theme (https://www.drupal.org/project/bootstrap). 
I am using the theme's 'Main menu' to display my links. The language switcher works well for me (changing homepage, Hero banner block and navigation into the appropriate language).

I would like to move the language switcher to the 'Main menu' and display it as an item only showing the inactive language. 

Could anyone please provide instructions how to do it?
I have a small module hosted on GitHub that does just that:
Locale Menu
From the README file:

Overview
Alters the href of any menu item whose title is &quot;English&quot; or &quot;Español&quot; to point to the translated version of the current menu item. If no translation exists for the current menu item, the link will point to the translated version of the homepage.

You'll need to tweak Lines 6, 15, and (especially) 21 of the localemenu.module file to match the name and language code of your language.
