Working as designed, quite well configurable

The only thing I would have liked is a bit more intelligence to assign new tags to a certain language, when tagging posts with a tag that is not yet existing. It’s quite a tedious job to tag them all manually. One other great compensating option would be to allow bulk tagging of items as belonging to a certain language (be it tags, posts, pages etc.). Is this technically possible in WordPress? I know in Joomla it is, don’t know WordPress yet enough to judge that.
