I have the following Used but not declared pref keys

• ignore_media_store_artwork -- removed in 65cf71d7
• blurred_album_art -- removed in ecf0f6b6
• album_art_on_lockscreen -- also removed in ecf0f6b65
• colored_app_shortcuts -- was changed on d7de0ae98 to should_color_app_shortcuts.
• make_widget_background_transparent -- changed on d7de0ae98 to should_make_widget_background_transparent.

I strongly think that this popover should be changed to an Android logging call, since these old preferences are explainable and do not cause harm.
