Unique identifier in browser title bar
Identifying which browser tab corresponds to which XG when tabs all say "Sophos" isn't possible without memorizing or clicking through each one. Prefixing the page title that populates in the browser tab with either ip address, hostname, or some other custom variable would be helpful when working with many XG's. The icon alone tells us it's a Sophos product, the "Sophos" text adds nothing useful.

adding to this - will also help to be able to customize what's presented in title bar based on which zone a client is accessing the page from for obvious reasons.
