support for folding code block when working on large livebooks

[epinault]

When using livebook it s really good but then when code block are large, it becomes sometime a long page to scroll down. Would be nice to be able to fold code block that I am not needing to touch while working on the others

Also being and to quick fold all code block too would be great! This would make the livebook quickly useful for just seeing the rendering quickly

I alsow wonder if sometime having the side by side frame between code and rendering as an option would be good

You can fold code blocks in the gutter today:

But I don't think there is a shortcut to fold all.

yes and no . Depending on how you structure it sometime you have many line that can be folded . Would really be nice to just easily collapse the block code itself

unless I wrap some large section into a module, that become also more challeging too

Note that you can also collapse sections:

Yes I know but some code section can be a lengthy or then you end up with a form and the visual separate making the usage a little clunky . Being able to just fold all code section then I can just evaluate and focus on the execution results

Exactly what Hugo showed in the video

I've been thinking that we could have that "hide code" per code cell feature for a while.

I was playing with Marimo the other day, and they have that: https://www.youtube.com/shorts/BWAJlfMod3Q

This could help to hide boilerplate code that the user is not focusing on while working on a notebook.

@epinault would something like this be helpful for your context?

[epinault]

Yes! That would be amazing! Exactly that !
