## Implemented Interfaces

RBShellPreferences implements AtkImplementorIface and GtkBuildable.

## Description

The preferences dialog is built around a GtkNotebook widget, with two built-in pages and additional pages for various sources.

The 'general' preferences page controls the set of browser views that are visible (artist and album; genre and artist; or genre, artist, and album), the columns that are visible, and the appearance of buttons in the main toolbar. The browser and column settings apply to all sources.

The 'playback' preferences page controls whether the crossfading player backend is used, and if enabled, the crossfade duration and network buffer size.

Currently, the library and podcast sources add pages to the notebook, for configuring the location and layout of the library and the podcast download location and update frequency.
