Layoutmanager best practice with Barrio

Ok, i think it is best to check out they /layouts folder inside barrio. There you can see how you can create own layouts in your subtheme.
In that way you can also reproduce radix layouts.

The customisation and new layout can be done according https://www.drupal.org/docs/8/core/modules/layout-builder → document.

But can you add screenshots of complex layouts? I may be given more suggestions.
