As you can see on my wip page, multilanguage support is planned. Don't expect to see it in the near future because there are some more important things to add in the first place. Multilanguage support needs a lot of codechanges, too...and currently I don't have the time for it. Besides the translators have to update the language files regulary.

As I said...not in the near future...
