When the now playing list is focused and you start typing a search bar pops up above the list which can be used to quickly jump to a song without filtering all non-matching entries from the list. I'd love to have a way to do this in other lists as well, such as the list of songs in a playlist in playlist view.
The reason for this is that I'd like to start the entire, unfiltered playlist at a particular location (without having to first queue all songs and going to Now Playing). There is a type to select functionality for file lists, but it only searches the current sort column. This means that it becomes entirely useless when sorting by e.g date, in my case it jumps to the first track in the list no matter what I type.
