NEW: Playlists Info
Playlists Info will display a sortable list of playlists in the current library (or in the selected source) along with their size, time and number of tracks. I've been finding this handy for eyeballing playlist sizes when managing music between iTunes and devices.
Additionally, the script can export a text file listing that information.
More info and download is here.
