Thank you! And great suggestions!

I focussed first on European languages as I'm learning French. But I'll put some more effort in improving the Japanese experience since it seems to be very popular.

> but if there's an intention for bookmarking languages of interest for separate collections of videos & transcription exercises I can say I'd be happy to pay, honestly.

Would a language selection box at the top be enough? Or do you mean a more elaborate way to switch between languages?
