Don't get me wrong I get the concept of cover photos on pages, but really enabled on every page?
I found that the pages across my website LGBTQIA+ Community look a lot better when the cover photo is disabled. So I just spent the last 30 minutes disabling the cover on all my pages apart from the following as the member has the ability to change them.
I know you can set a default cover and that is great but you don't want to see the same cover everywhere and unless you go to every page designing a cover for the pages they are a bit redundant.
I think cover photos should be disabled by default apart from
Homepage - Set to Vistors Only!
Administrators have the option to enable the cover where they want to instead of having to manually disable them all.
It definitely seems like there's some missed opportunity with 'site wide' applications to theming like this. I agree that there are some pages that I might want to have a cover, but generally, I don't.
