1) When I click on the General Styling tab, the predefined color schemes are greyed out.
I just did another search and discovered help at this link:
Why did I click on it? Because the image in their preview showed that the color schemes were greyed out.
Because it’s not obvious, it would help if you included some descriptive text that all the color schemes are greyed out until you click on one!
Doh!!
Answer:
3) Breadcrumbs … (new term for me)

I’m obviously more awake today. Hope my research has been helpful to others!
