Can you add a screenshot of what this looks like? I'm afraid it might get cluttered...
Show submitter's full name on dashboard
Review Request #2191 — Created March 8, 2011 and discarded
Changes submitter column in dashboard and other data grids to show full name instead of username, when possible. In most places full names are already used in RB; plus it especially helps in corporate environments where people use numerical usernames.
Manually verified that full usernames are displayed.
I'd be much happier if this introduced a new, optional column, that displays the full name.
