Overview of all sessions by program

Hello,

For me, it would be useful to have a summary of the programs to read before starting them, to help you memorize the concepts and make them your own. And in the same way, to have an overview and be able to go back to certain elements of a program in progress.

I find that you're a bit in the dark when you're in a program. We need to be able to return to the same concept several times.
