I love this feature! However, the icon for the links do not show up.

- name: "victron"
  logo: "assets/tools/victron.png"
  url: ""
  quick:
    - name: "gui-v1"
      url: "http://192.178.1.128/gui-v1/"
      icon: "fa-solid fa-arrow-up-right-from-square"
      target: "_blank"
    - name: "gui-v2"
      url: "http://192.178.1.128/gui-v2/"
      icon: "fa-solid fa-arrow-up-right-from-square"
      target: "_blank"

Thanks for your feedback @grasshide! I'll look into it asap!

Indeed, the quick icon does not appear unless the parent item also has an icon defined. I can make the icon appear if I set icon: true to the corresponding item, but that messes the padding of things, as all of my items make use of logos.
