Pinyin Display in Expansion

Hi Chinesepod,

i think its better to decide which form of Pinyin will be used. Showing the tones 

by figures (1,2,3,4) is harder to catch, especially when using the other way in 

same lesson.

BTW if you use the figures, the sentence becomes too long.

Sorry for the bitching!

Anyway I think your side is great!
