Please add a scroll bar to the top of the contact list.

There is one at the bottom, but because the list header does not freeze to the top when scrolling, it makes locating content difficult for lists that have lots of columns.

There should be a frozen header, with the scroll bar right above.

Because when a vertical of 50-100 contacts are displayed, with lots of columns spreading horizontal, it is so time consuming to have to scroll back and forth to be sure you have the correct info.
