I've used your new format several times now to verify contacts and add contacts. It requires many more steps that the old version. I do not see an option to add another contact unless I go back to my original list and start over. Option to delete old contact information? I can remove from view but not the list?
In list view, you can delete contacts, by placing a check to the left of their name. Hit More Actions and then Delete. Delete will delete them from the account and remove will remove them from that particular list.
