One of the things that irked many users when iTunes 11 was released was the inability to open more than one window. Some users kept an iTunes Store window open all the time; others liked to open playlists in their own windows, to make it easier to drag tracks to them and edit their contents.
AppleScript maestro Doug Adams has released the $5 Playlist Assist, a new tool which replicates some of the old iTunes playlist window features. Playlist Assist gives you a floating window that you can use to create and edit playlists. But you can also get track info, change tags, play tracks using Quick Look, and export playlists.
I’ve been using this for a while in beta, and I’m quite impressed by its flexibility. If you want a great tool for creating and editing playlists, you need Playlist Assist.
