Suggestion to put dificultuy

Dear
i suggest to add the difficulty column to each content so i can choose the suitable for

thanks

After going through texts in Beginner and Beginner 1, I choose content which I find interesting, and that doesn’t have too many new words (90% is obviusly too much, while anything from 0 to 25% is OK).

We are planning on adding a difficulty indicator in the Library very soon.

thanks
