Visual indication that a process flow is running (Universal)

I would like to see that the GUI shows a visuals indicator that a user is in a GUI flow. 

Now when you go from flow starting task A to task B (with a for example a decision node or HTTP requests in between) the user doesn't see that a next task is coming up. 

Implementation could be something like a tsf_send_progress idea where are user is aware that the flow is getting info, making a decision or whatever is in the flow.
