how to search exercices rapidly without missions

I have read mission will desapear in june 2020. As a teacher I was using the misions grid ALWAYS to know all the kind of exercices was possible to find in one specific area (arithmetics, algebra,...)

The most important was the general mision

Or for exemple algebra basics:

In this grid using the cursor was easy to find tasks to some of my students who needs to practice more one or another kind of exercices, or to give more material to investigate. As a teacher trying to find this materials without this grids it seems nearly impossible. How is possible to do this if you clasify all only by levels and not by big areas (arithmetic, algebra...).

I WANT TO KNOW AS A TEACHER A GRID WITH ALL KIND OF EXERCICES. Can i get it in other ways?
