This idea has been merged into another idea. To comment or vote on this idea, please visit A-I-11441 For "assigned to" and "watcher" or other applicable lists have users email addresses displayed next to first and last name.
Assignees are currently listed by first and last name. In a large organization, it's not uncommon to see users with the same name. Email will help to distinguish the appropriate user.
As more of my organization has begun to adopt Aha, this has started to become an issue for teams who need to assign work to users who have the same first & last name as other users. Having unique profile pictures is a workaround, but it's not great.
