I find the Chinese characters on the flashcards to be quite small, especially when compared to the size of the fonts used for the English and pinyin letters. Also, for characters with lots of strokes, the images are too small. Please make the fonts larger!!
In addition, how about presenting the characters on the flashcards using Kaiti (kaishu) instead of the form you currently use. Isn’t kaishu generally recognized as being the easiest for beginner and intermediate students to recognize?
Thank you for considering these two suggestions!
