Another little thing that maybe improved: The correct answers shown after doing a kanji cross seem to be not in any particular order. For a quick check of the mistakes (or correct answers) it might be better if they would be in the order of the crosses. Maybe it would even be more easy to look (and learn from) the answers if there would be the first inserted correct kanji and then the terms used for that kanji and then the next kanji and then the next words. Just an idea. (example below; bring words with kanji in order and pair with kanji)
