Thanks a lot Ray.
May I give you some proposal for future development:
Maybe you should change the database scheme to save content depending on selected language.
So when you have added some content with one language and you switch to an other content, initially the content fields are empty, because of the different fields used from DB.
When editing the content, it would be helpful, to have a button, that brings up a dialog, with two Richtext-fields, one for original language and the other for the selected language.
Just only an idea. But I think would be very helpful for localization.
