-Once again, I want to thank Paul for his reply. Now a few tips from a new user's experience if another stumbles on this post.
After looking at all of the cool example pages, articles, and the like included in the template, I would give the first tip: unpublish them. They only crowd out your work and might confuse you. They did me. Don't delete (trash) them. When you need to review an example, if it's gone, you're in trouble. I know I had to reload a template and start over after a fit of trashing 'unneeded' items.
Another tip, don't read the documentation until AFTER you have played with SP PageBuilder. It might not make sense. Play around a while, then read it. It made a whole lot more sense. Just don't skip the reading part.
Speaking of documentation, read and watch everything you can about Joomla 4 (if you are using it), then fill in the gaps with Joomla 3 stuff. I found enough differences to make a lot more sense in understanding the changes, then going back to get the foundation.
These are just my tips. Everyone learns differently and starts from a different point.
As long as Joomla remembers a CMS is a CONTENT management system and not a page builder, I will be here for a long time. I'm old school—seperate content from presentation.
