Hi!
My english is not so good, but I will try to explain what I mean.
There is an "active" way of studying how to write a character because you actually have to write it, and there is an "active" way of studying the pinyin because you actually have to type it in, but there is no "active" way of studying the definitions.
I believe that you learn a lot faster when you constantly have skritter test you on a right or wrong basis. Having to grade yourself on how well you know something is not that great, because its "passive".
Is it possible to find a new way of studying the definitions? It could be that you would have to chose from 4 different definitions and click the right one, or it could be that you actually have to type in 1 of the correct definition words etc. Just something to make it more "active". I hope you understand what I mean.
There are a lot of other potential ways of studying that you could add in the future. How about seeing an example sentence with a space in it, and then have to chose the right word to add, like:
__ __很早出门,但是我还迟到了。
A. 可是 B. 不过 C. 虽然 D. 果然
Maybe something to consider?
