Additional lesson information?

Could we get a bit more word statistics in the lesson information?

In addition to what is already there, I’d like to see:

  1. Total number of unknown words (i.e. new words + lingqs)
  2. Percentage of known words in the text: (unknownWords / uniqueWords)
  3. Percentage for all 4, 3, 2, 1 coin words/lingqs in the lesson (i.e. measure of word difficulty for the lesson)
  4. Percentage for all unknown 4, 3, 2, 1 coin words/lingqs in a lesson (i.e. measure of unknown word difficulty)
    This helps me better estimate the difficulty of a lesson and better assess how enjoyable it will be to read.

Thanks for your feedback and suggestion. We will see what we can do.
