 * Monolithic 'press_space' action was split into 'add_item_to_playlist', 'toggle_lyrics_update_on_song_change' and 'toggle_visualization_type'.
 * Sorting actions were rebound to Ctrl-S.
 * Support for range selection was added (bound to Ctrl-V by default). In addition, sorting, reversing and shuffling items in playlist now works on ranges.
+* Support for selecting found items was added (bound to Ctrl-_ by default).
