The Hierarchy report is great. However, I think it would be better if you also got a green tick next to Initiatives and Releases that were completed / shipped. I think this would be a better visual representation of delivery against a goal.
Thank you for your idea. As noted in the comments, it is possible to add the status field to the hierarchy report. It is also now possible to include the progress field which will show % complete for each record.
Given these options and historical support for this idea, we are unlikely to add a checkmark icon for completed records. We hope you can understand.
