I'm using a text widget because it gives more control.
My question is what relationship the Visual tab has to what the text widget in Page Builder is doing.
It seems that I can make whatever changes I want in Visual and this doesn't matter because the site will look like the lay out within the text widget.
I get the feeling I'm missing something here. I would have thought that the visual tab would give you a visual representation of what the page would look like, and changes made within the text widget would be represented there.
Also good resources for WordPress learning, preferably text, welcome.
