The main panel contains several tools to navigate your collection. The most visible of these is the Tree which contains various nodes that allow you to browse content by different attributes. To navigate, select and browse by any node, using the mouse or arrows keys, or by typing text. To fine-tune the results, you can use the Track Browser to select particular attributes or the Search bar to search the contents of the selected node or the entire library (configurable).
Starting from the top, here's a brief description of the various other functions in the main panel:
The View toolbar allows you to switch to Album Art view and/or enable the Track Browser.
The Navigation toolbar allows you to view where you are in the Library hierarchy, and change locations.
The Shortcuts toolbar quickly brings you to various nodes that may not be visible, or switch back and forth between nodes.
The Now Playing window displays the currently active playlist.
The Album Art window shows art for the selected or currently playing track (configurable).
The Player displays the currently playing track.
The Status bar under the tracklist shows information about currently selected or playing files, along with status information about any ongoing background activities. Any background activities can be terminated, or increased/decreased in priority by right-clicking on the Status bar.
