When connected to Whaller, you will note that there is a header bar, present on all pages.
The "My spheres" menu (on the left) lets you access all of your spheres directly. The number next to each sphere indicates the number of unread messages (Total in the title, then in detail per sphere)

Close the session or close all sessions (several computers/devices)
What is the difference between "Close this session" and "Close all sessions"?
Close this session: Close Whaller on the computer that you are using.
Close all sessions: Close Whaller on all devices (tablet, smartphone, computers,...) where a session was open. This is especially useful if you are using a shared computer, or if you left someplace without checking if you closed your session.
