> Would it make more sense for the load more to be at the bottom of the e.g. contacts record section?
And then when you click it, it will be adding the new records to the bottom of the list as well where you would be expecting them?

> Also if the load more button is at the bottom of the list, could the "contacts" title in the above image be left aligned so as to be more visible?
