I've customized the favicon in the super admin panel but in SM15 release notes it says:
Added: System administrators and domains can now upload a favicon icon to use for webmail
How can we customize the favicon by domain? I tried loggin as a domain admin but there's no "Login Display" tab in the genreal settings. Did I misunderstand what you meant in the release notes? Isn't it possible to set a different favicon for each domain?
