I would like to be able to lock the header while I am scrolling through large contact lists so I can make sure my contact setup is uniform. Also, I would like to add the "list" to the column header to make sure my various contacts are included in the list for bulk mailings (ie, if I want to send a buyer a list of all my lenders, I can quickly go into contacts/sort by lists/select lender list and forward to my buyer.
