Some essential question types for Chinese Language learning

Hi, I am a secondary school teacher from Hong Kong, I teach Chinese Language. I found that opigno is a very useful learning system, and I love to use it as a teaching platform. Yet, I have 2 suggestions for you guys to improve opgino, in order to make it fits in with different subjects. Fill in the blanks The question type is a MUST in teaching Chinese and English. It helps to test if students understand the meaning of the words. It should support single or many blanks in one question, blanks can be randomly or manually placed in a paragraph. Drag and drop for rearranging order of the sentences Sentence rearrangement is common for writing classes among the early primary students For example, 56/89/23/1/7 (the numbers represent phrases), the answer should be 12356789. I would like to know if you can make each phrases "drag-able", because kids don't know Chinese character coding input methods. Thank you!
