Multiple editors on the same page

[aleckravets]

What is the best way to build a notebook editor app where you have multiple cell editors on the same screen. Like in this VS Code extension - .NET Interactive Notebooks.

The number of cells in the notebook may be up to several hundreds, so If I create editors for all cells at the same time it will kill the performance.
Is there a way to show a lightweight read-only version and only create actual editor on focusing the cell? How it's done in the mentioned VS Code extension?

Any help is appreciated

As long as you don't show all thousands of editors at the same time, you can just reuse those monaco editors that got scrolled out of the view, but keep all the models.
Afaik this is how notebooks are implemented, but @rebornix knows more.

@hediet Is this doable in a scroll-based notebooks app?
