Now that we have Japanese support, I'd like to send out an idea that I'd had months ago, namely cross-training Chinese and Japanese characters.
With most characters, this could be as simple as learning the character with both pronunciations and then testing it with one or the other. This would effectively double the characters I know in both languages, which are (except for the 100 or so super easy ones) largely mutually exclusive, and (hopefully) cut down on my trying to slide past my teachers Japanesesy pronunciations of Chinese.
("Kore wa nan desu ka? 道"
"Errrrrrm... ? Dào? No? Jou?"
"...Michi.")
