Notebooks
### What is this PR for?
Currently, if you have a Notebook large number of,
There is a sharp decrease in performance of the Code editor.
The number and Paragraph creation of the Notebook does not have a

We are should always use the Code editor of the same performance.
I had to print a Notebook list only if there is a request.
There was quite a lot of performance improvements.
