Google+ has a new interface that brings a lot of changes. It's not yet available to everyone and that's because it rolls out over the next few days.
The new interface has a vertical navigation bar that lets you reorder and hide apps. When you mouse over an app, Google+ shows a list of quick actions. There are two new pages in the navigation bar: a hangouts page that lists the invitations from the people you've added to your circles, as well as a list of popular hangouts and an explore page for "what's hot". The list of circles is now displayed at the top of the page, the search box is larger and the chat gadget has been moved to the right sidebar.
