Hello I wanted to make some suggestions that I think would help make the site easier to use and more helpful for reinforcement. I sent them through the help desk thing, but haven't heard anything back. Figured this would be the next best place.
The first is that it's a bit difficult to find the last lesson you completed. Right now you have to go to the classroom, click show completed items, then scroll through page by page to find the last lesson you finished. I often go back to refresh on the kanji and some lessons that the drills don't quite matchup in.
The second is for the kanji drills to have the on'yomi, and kun'yomi pronounciations along with them. A lot of newer drills don't include the on'yomi and kun'yomi for kanji and it's getting tougher to remember the pronounciations for more complex sentences and uses of the word. I think a least listing them by the side in the way that a lot of real manga does it will help reinforce the word and help comprehension a little better.
