Suppose I type "ting" and I have a file called happyThings.wav. At the moment, it's not immediately clear that the T, i, n, and g, of "Things" are the matched characters, and the only characters after these are s, ., w, a, and v. It would be nice to highlight the selected characters in some way, so as to allow users to easily see if they can filter what they want by typing, or if they are forced to scroll down.
