Good idea, still work to do!
The program is very good, the idea is amazing, but still there are some things to be fixed or add. For example to be a good tool to study for the Japanese Tests there should be word examples, so will be easier to for us to remeber. Sometimes in one kanji there are a lot of english word, there should be the Japanese word for all of them, so is easy to know in which words the sound of the kanji changes. I´m looking forward for the new version, the program itsel is very uselful!
