Hi all,
Firstly, thanks to the developers for this great tool. It's really fun and effective.
Now a suggestion: Could bopomofo (Taiwanese pinyin, basically) be added to the word-sets and added as an option instead of pinyin transliteration? Having bopomofo recognition would also give an easy way to input the pronunciation of a character for when that function is added. Since they're made of the same strokes as ordinary characters, I assume they would be easier to have the engine recognize than drawn Roman characters.
