Pinyin alongside hanzi for Android app.
Doing the Chinese tree I'm finding it difficult to understand the TTS voice as it speaks very fast and there's no option to slow it down, as a result it's often difficult to discern which tones are being used. I know I can select each character in a sentence to hear it spoken individually. However, I personally feel that having Pinyin alongside the hanzi (or in the drop down menu for the character, in addition to its translation) would make learning the pronunciation of words much simpler. Also, speaking exercises please : )
