I'm currently re-building a website on WordPress. 

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. 

Seems, not. 

Any ideas? 

Also good resources for WordPress learning, preferably text, welcome.
