What language courses do you wish Duolingo had?
After finishing Cantonese for Mandarin speakers (only about 300 lessons), I'm out of new lessons to continue my streak and the languages I want to learn are not on Duolingo. I know these are more niche languages but I'd be back in a heartbeat if Duolingo offered courses for Tibetan, Mongolian, Uyghur, Manchu or even Thai. Until then I'll just be enjoying the green birb memes
