Are there more or different themes/colors to customize the home screen for emails (Personalization of Xfinity Connect)? I see that I can select a pull-down list of themes/colors through the email settings (basic settings and theme), but are there more options or ways to customize the way the screen looks visually? I don't want to reorder the screen, just have more choices of colors and themes to choose from. And have choices for borders and the space where the emails are displayed -- colors, styles, fonts, etc. And different subtle watermark themes and colors.
