What's next Solo Learn?

Question

I'm playing with sololearn since couple of months, and I feel that the great part that is missing is an important and valuable part of the modern web development: css precompilers (scss, sass, less), JavaScript frameworks (ReactJs, AngularJs, VueJs).

@Sololearn: you have some plan for what's next?

And you guys? What you think is missing?
