I noticed that if you kept the home page open, it will display when your friends come online. However, it does not merge those players to the far left side to display in order that they are online, if that makes sense. Instead, you have to refresh the page for it to display them in order. My suggestion would be to make it automatically merge the players to the left if they are online without having to refresh the page.
