When the proof’s workflow reaches a gatekeeper or the approver in the final step, icons will appear next to each comment like the example below. The comment icon indicates whether it is to be ignored or actioned.
Ignore (not marked): grey dot with a white dash
To-do: red dot with a white tick
Done: green dot with a white tick
Note: You may also see a grey got with a white tick. This indicates that the comment was to be ignored (not marked) however it was actioned.
