I find myself switching regularly between tabs of my own Home Assitant instance UI and the home-assistant.io site when trying things out / browsing the docs. Unfortunately they have the same fav-icon (the blue home assistant logo) which makes it hard to distinguish them especially when I have multiple tabs open in the browser. It would be nice to be able to (easily) customize the fav-icon of my own Home Assitant, or maybe just ship with a slightly different default icon.
