Please put the Sign-out in te Lower-Left Expanding Sidebar, so when we mouse over we in addition to seeing those five little icons: "Change Theme", "Share Feedback", "Keyboard Shortcuts", and two more, we see a sing-out icon that we can click on.

Right now, we have to go to account, and then scroll down.

Much simpler to add the icon to the Lower-left expanding sidebar.

Please give it some consideration. Thank you.
