Hi. I wanted to add the word 人 (hito) to a lesson, but this word just appear in hiragana in the search results. Because of that, the word is also shown in hiragana during the lesson.
Also, I couldn't find the particle か in the dictionary (but I could find all the other ones).
And finally, the tags "adjective-い" and "adjective-な" are shown in the questions as "adjective" without the い or な. This is a problem when you have words like 小さい and 小さな, that have the same meaning and the only difference is the tag. Anyway, the tag is shown correctly after select the answer.
