Apple has made a minor revision in the MobileMe preference pane's Back to My Mac tab in Mac OS X 10.6.5. Previously, that tab showed a status dot in red, yellow, or green, along with an explanatory text message, to indicate whether MobileMe was active and communicating correctly with Apple's servers. In this revision, two additional status dots and text messages are added for File Sharing and Screen Sharing. A green dot indicates the service is on; red, off. Putting status about those two items in this tab means you don't have to switch to the Sharing pane to check whether either of those services is active.
