Filter menu parent dropdown by language for multilingual site? I am working on a multilingual site that has about 60+ pages per language. When an admin user wants to add a page to the navigation menu its becoming quite the task because literally every single link (from all languages) is listed in Main Menu. Its even more confusing because the site has some cases where French and German are in the menu twice because the site has Canada-French and France-French as a language. 

Is there any way to manage the navigation menu better? Like if I select German for the language could the menu dropdown automatically filter itself to just show the German nav items? Right now we have a list of about 300+ items in the dropdown :(
This seems to be the issue page for this problem: https://www.drupal.org/node/1242288. There are patches but as Jose Reyero points out, it would be only a partial solution.

There is a https://www.drupal.org/project/content_menu which enables you to first deal with the menu and then with the content instead of vice versa. Haven't tried but seems nice. This combined with Fixed language menus (provided by Menu Translation at admin/structure/menu/manage/menu-mymenu/edit, Multilingual options - Translation mode) could clean up the menu interface nicely.

Personally, I usually just don't bother dealing with the Parent item, I just head to the menu interface after creating a node, and drag my item, which will be at the bottom, to its place.
