> It is sometimes unclear why a Processor is not running, if it is due to 
> backpressure. Recommend we add an icon to the Connection label to indicate 
> that backpressure is configured. If backpressure is "applied" (i.e., the 
> backpressure threshold has been reached), that icon should be highlighted 
> somehow.
