i do believe that it will be better allowing I mean admin to add more than one language to a post, that means from the plugin adding setting once can add as much language as possible. Please that is the feature that I would love to see. It will not be limited by 5 or 6 language.

please let your next version come with this feature.. also it will be sweet if when added lot of language from the admin section on the post editor section I can select as much language, I can click select all and add to a given post
