Hey Duolingo, thanks for adding the kanji for dog, could we also have the kanji form (rather than just plain hiragana) for: meat, 肉, vegetables, 野菜, tea, 茶, I, 私, and to drink, 飲む. Cheers, ありがとう！
I have to say that while increasing the number of kanji is necessary for actual proficiency I don't see how they can do it in such a limited framework. Joyo kanji are far too numerous; picking and choosing which ones to include or not include would be entirely subjective. This is the reason I am in favor of breaking up the program to: Introduction to Japanese; intermediate conversational; advanced, etc.
中、毎、高い、低い、長い、短い、夢、広い、色、... Once you start getting requests for more kanji surely there would surely be no end.
