Playlists appear in the left window. The library is always the first list. All other lists can be deleted and their position in the window can be changed by drag and drop. Playlists can be created in several ways.
Deleting and renaming playlists
Playlists can be created by pressing either the new or copy buttons at the bottom of the playlist window. The former creates an empty playlist and the latter creates a list contains the tracks currently displayed in the tracks window. Playlists can also be created by importing a playlist file.
To delete a playlist right click on it and select delete from the popup menu. Unless the list is empty, you will be prompted to confirm the delete request.
To rename a playlist right click on it and select rename. Then type in the new name and Enter to complete the edit. To abort the edit and restore the original name type Esc.
You can change the order of playlists (except the library) with drag and drop. Select the playlist or playlists to move. While keeping the left mouse button down, slide the cursor to the playlist just before the point you want to move the playlist(s) to. As you move the cursor the destination playlist changes color. Release the left mouse button when you reach the desired destination.
