Order Jupyter notebooks

[tristan0x]

Currently documentation in Jupyter Lab appear unsorted. A beginner don't know exactly where to start:

Suggested change:

1. prefix name of every notebook with a number 01, 02, ...
2. List in prelude of every notebook the topics addressed.

Hello
@WeiliangChenOIST What do you think of the suggested change?

[WeiliangChenOIST]

good suggestion, but note that some of the pages have no notebooks (the .rst ones) and they need to be indexed as well.

Hello @FrancescoCasalegno
Just to be sure that I am not missing something, do you know if there a way for people using Jupyter notebooks to have the proper order somehow?
