I agree with this request.
I often find myself having to manually change the background of each and every block to match the branding requirements in my assignments. And if the background is dark, I also end up having to change the font color in each block as well.
That's a lot of extra work. I think it would spare users a lot of time if we could have select "Default background color" and "Default text color".
And the default background color would preferably affect the top & bottom bar of each chapter, because right now it looks kind of janky when we try to brand something in Rise, and it just cuts off to the default white.
I read in the automated email sent with feature requests that "we estimate the value it could bring to our products.". Wouldn't you agree that being able to say something in the lines of "Match your company branding requirements 100%" is great value added to the USP list for such a minor feature?
