On the device details page, the "last user" is also displayed as the "display name" (in parentheses) at the top.
I would also like to see this additional display name in the “Last User” column on the global “Devices” view (menu item on the left).
This is very helpful when the SamAccountName is generic, as it allows you to find devices assigned to a specific user.
Example:
domain\B00011 (Last Name, First Name)
