There doesn’t seem to be a way to edit these in any form. As of now, they’re stuck as big grey banners with small white text. I cannot edit the text size, I cannot change the color, I cannot shrink down the banner size, I cant even remove the banner altogether. The only thing I seemingly CAN change is adding an image to the banner which will have a grey overlay over it, making the image dark. I simply don’t want a big grey ugly banner at the top of my collections pages, or would like to shrink it.
