We can add a column what shows when a report is created to views and reports, but we can not add a column to show when a Dashboard was created. We need to be able to see when a dashboard was created just like we would for a report, project, etc.
We need to be able to see tasks assigned to a team even after someone has "claimed" it. There is no filter that allows this in the My Work widget and disappears from the Team widget too. Meanwhile, other team members still need to see it and keep it on their radar until it is completed.
