I was playing around with ACF 5.8 and the Gutenberg blocks and I found this nice Column block from Gutenberg in which you can add your own blocks (as on Twitter). But since there is no way to edit the main Gutenberg blocks I was hoping there would be an alternative to this.
I used to create the same idea with Flexible content but since we want the blocks to be as lightweight as possible this would probably make it too heavy. I would love to be able to make my own Column layout.
TLDR: I would love a field in which you can add your own Custom block again like the standard Column Gutenberg block.
