Smart/configurable exclamation mark#5138

Sometimes an output is simply unhelpful, e.g. the color output from a shape analyzer when I only need the shape type. However if the output is blocked, an exclamation mark is shown. I wish the exclamation mark could be configurable, especially for multi-output logic devices.

i wish that conflict marker could be ack’d and then it goes away … like grammer or spelling errors that you tell the wordprocessor to ignore this instance
