It would be usefull if you can use settings in the people column to select display of full name, first name or last name. If no name present then (off course) e-mailaddress.
This would be really helpful, especially if people add their own personal profile pictures. With images being so small, it’s often difficult to tell who is who at a glance.
This would be very helpful especially when there are numerous users in a people column. Photos are small and currently need to hover over and click on X others.
