Hello,
I love the page builder but there is one thing bugging me:
When I want to put in a nested layout in a cell with the layout builder widget, I can not give it a name. When I open a page I can only see that in the cell there is a nested layout but I can not see what.
For Example when I add a text widget, I can give it a title and from the post edit page I can immediately see what content is where. If I can not see the title I have to open each widget to see what is actually inside there.
To make my point clear, here a screenshot:
