Textquick is a small utility that performs an analysis of the messages currently stored on your device, making note of the senders and recipients. TextQuick then presents you with your list of contacts ordered according to messaging popularity.
Contacts that you exchange messages with most frequently are listed at the top and those with the least frequent correspondence are further down the list. Contacts with whom you have not exchanged any messages are then listed beneath in alphabetical order. There is also a search bar where you can type a contact name (first or last) and the list will drill down as you type.
