It would be helpful to be able to change the size of the font for the playlist when it is in windowshade mode. At high resolutions (1600x1200 on a 17in monitor) it is nice to be able to change the font for the playlist but it is still too small when when window shaded.
It allows you to specify typestyles/sizes that are "universal" (your choices remain in effect when you change skins). It allows you to select any of your installed fonts for the title display (both normal and doublesize) and for the playlist (both standard and windowshade mode). Not all of its features work on all Windows operating systems, but you can try it out and see if it helps.
