Custom <div> banner above the Editor

[jbudd]

Welcome to the forum sambarlas.

This is not quite what you are asking for but it is possible to change the image & text in the header and make them link to another page:
In settings.js

header: {
    title: "Red in Tooth & Claw",
    image: "/home/pi/.node-red/node-red-static/myimages/redfox.jpg",
    url: "https://nodered.org"
},

You need to tweek the CSS to make image & text larger and move the main page content down.
