About the scoreboard on the board page

The scoreboard is a column of numbers below the toolbar.

Here, you can see:

Waiting for Submission: The number of inquiries where the "Resolved" mark has been removed from the card.
No Assignee: The number of inquiries without an assigned person.
All: The total number of inquiries either for all or for the selected account.

The numbers on the scoreboard are clickable and can help prevent overlooked submissions.
