I think it would be helpful for troubleshooting showing which action or option is executed, in a similar manner to how the trigger is shown as Triggered.
These would be helpful in troubleshooting.
edit: for clarification. This is when in the automation editor when an automation is triggered the actual trigger is shown with a color band above the trigger. It is a slick and elegant way to display what is going on and would be that much better if it could be applied to the actions as well.
