I know this might be too early, but may you add standard Italian? It just feels weird not having it amongst the major Romance languages on this website. Of course if this intereferes with the development of the other courses, then please don't feel obligated to add it. Merci, Danke, Gracias, Obrigado, and Thanks.
The thing is Italian and Romanian arent international languages (although neither is German) and they dont have Arabic or Mandarin up there yet OR ways for many people to learn English (French to English) for example. I think focusing on making the 6 international languages interconnected makes sense for them first.....
