Improve the contact search function so that it more accurately finds the correct person you're trying to message. When i want to message my wife, Valerie, I have to type out the entire word Val to find her. She is the only contact in my Phone who's first name starts with a V. When I type V, my friend Adam is the first result (he doesn't even have a V in his full name). I also have my wife as a pinned conversation so that's another item that should be prioritized.
