Oh I found both spots, just not how to not show the featured image when I want both the featured image and the full size gallery image same size. I had checked both those spots so many times but did't see the option for featured image display or not display.
Well that explains it for Cornerstone posts! I was going crazy having made so many sites with X to Pro, thinking i had posts using Cornerstone. I have 4 versions of Pro and must have used Cornerstone that was built in on Pro sites. I was thinking Cornerstone was removed from making posts with the last addition of X. Thanks for the clarification.
I do recommend ANYONE with a good size site to go PRO. Great styling availability! Well worth it.
