Yes, currently the tutoral screencasts don't match the deployed system.
Our apologies, we are working hard to re-author all the tutorial materials.
The IDE no longer attempts to connect to MQTT or do any other runtime
actions. You will get connection status in the viewer, but only if you have
an error, if you see no connection status, its either because you are not
using MQTT or because your connection is OK.
Hope that helps.
