Google Classroom - new improvements?

Currently, we have been using Google Classroom for all or any assignments or homework. I do think we can improve on some features such as adding on a curriculum from the teacher's side.

e.g. As a teacher, I can create subjects and within those subjects are lessons. Then if I am handling a current subject within that class, I can "run" a new class with all the lessons and any attachments (readings, references, and exercises).

It works like a template ;)
