First off - I LOVE what Japanese pod is doing. I've been listening for a while and although I didn't take advantage of the special content during the free trial period, I decided to buy a full membership just because the podcast lessons are so valuable to me. What the Japanese Pod crew is doing here is amazing, and I want to support their cause. Please keep up the fantastic work.
Alright, that being said, I am making an official request. For the Kanji Corner, it would be great to see examples of common words written with those Kanji that use the Kunyomi and Onyomi readings. Just a few of the more common ones. I'm also pretty sure there would be a way to search for that particular Kanji and show what lessons used it in the Dialogue. I think it would be a great feature to present a dynamic list of lessons that use it, and then click to show it in action.
It would also be nice to expand this section with more in-depth lessons about Kanji. ... and with the common request of stroke order, I'd like to add stroke direction.
