Current behavior

I have a test Livebook (see screenshot) and was experimenting with deploying it as an application. I went to the local preview option and expected the result to include not only evaluated cells but any text sections and markdown, however I only see certain cells.

Expected behavior

The deployed Livebook to contain all of the cells in the document.

This is the Livebook I started with

This is the preview.

Correct! You can use Kino.Markdown or similar to create text as output, which is then part of the app. The text itself is assumed to be documentation/reference.

Just an observation, but for my use case that makes things a little difficult, as I wanted to write a blog like page with lots of text and a few interactive cells.

@josevalim It would be ideal to have a way to accessing the markdown cell content from code cell as variable.
It can be something like Livebook.get("cell name")

I'd say that's even more unlikely and you should prefer to use Kino.Markdown instead, although we may have an option to keep text in the deployed app.
