Header area for Modern Pages

I have the new editing features on my dev tenant but they have not made it to my employers tenant just yet.

These are great features, love the new column templates and the ability to change the header image

But! Modern pages are still unusable for my employer.

There is no way to scale the header image, therefore your images are set to fit the space and this destroys the resolution, hope this is changed before the final release.

We still need the ability to either remove the header and shrink the white space, you can choose to not have an image but it still leaves a big gap between the Page Title and the Page Body.

Users do not like a lot of white space between these elements.
