New HSK Chinese for Pc

This app is super simple to use - which is a positive! I'm currently studying Chinese in China, and most of the resources I find are too complicated. I really appreciate the simplicity of this app. I have some simple recommendations for the developer that I think could maintain the simplicity, but really aid in effectiveness: 1.) Give an option to randomize the vocabulary. Having everything in alphabetical order is helpful at first, but then it hurts my learning. If I don't know which word it is, I can remember which pinyin letter started the previous word and guess the character without actually having learned it. 2.) Have an option to hide the pinyin, audio, and definitions in the practice mode. The test mode does this, but it would be nice to toggle it on and off while in the practice mode as needed. 3.) Allow the keypad to scroll through the list. For example, the left/right buttons change to the previous/next word, and if the pinyin, etc. is hidden, the down button would reveals the pinyin, audio, and definition. 4.) Offer a way to track scores in the test mode. Ie., the up button marks correct, down marks incorrect, and both proceed to the next word. The score count is shown at the end. 5.) Because each HSK level has a substantial increase in vocab, it would be really nice to add one more list option. You already have the "To-Learn" and "Already Learned" lists. It would be nice to have an option for a "Learning" or, "Practice" list. If I had this, I might add 20 words at a time to practice. When I've learned those, I can remove them and add others. Hope these suggestions can be helpful as you improve your app. I'm still happily giving four stars for this. I love how quick and easy it is to use!
