Before updating, the header icons (Create, Notifs, User, etc.) floated above my large banner image.
I had the same problem of a tiny banner image after updating. Adding to Custom CSS makes the image larger now, BUT it's putting the row of header icons to the right edge of the image -- instead of on top of, or even underneath -- and it looks really dumb.
Is there a way to simply have a full-width or contained large image, with the header icons beneath it? Or on top?
Thanks!
