The 'Now Playing' queue shows the currently active playlist, with the currently playing Track appearing in bold. See Playing Audio Tracks for more details about adding/removing Tracks from the queue.
The Now Playing queue can be viewed via:
|1.||The Now Playing node in the tree|
|2.||A dialog in the main panel (enabled via View > Now Playing). This is useful for dragging/dropping tracks into the queue from other nodes.|
|3.||A dialog attached to the MiniPlayer|
The Now Playing dialog can also be used to edit playlists, allowing you load, reorder, randomize, burn, etc. playlists easily.
