The Builder is a powerful tool when it comes to creating content, and you will realize this at the latest when you create complex content.
Unfortunately, you can quickly lose the overview when the structures become VERY complex.
This example is not as complex as the ones I have already created, and it should only serve as an illustration:
I think you can see what I want to achieve.
What is finally the best design solution is probably best asked with the community, my suggestion would be at least level deep structure-giving elements such as bar, row, grid, column, div to give a better recognizability.
Maybe not the best solution, but i hope there are suggestions from you or the community?
