The cover used to be a full-bleed image, either yours or one of fifteen generated backgrounds, and its corner showed a logo file whenever the brand had one.
Now the intro form has two new choices. Cover switches between Image and Color: pick a colour from your palette or type any hex, and the cover paints it flat with the text in whichever ink reads best on it. Corner switches between Logo and Brand name, which sets the name in your display typeface and leaves every logo file where it is.
Both were asked for by a studio the evening before, and neither one changes a page until you pick it.
