+/** @file disobedience/choose.c
+ * @brief Hierarchical track selection and search
+ *
+ * We now use an ordinary GtkTreeStore/GtkTreeView.
+ *
+ * We don't want to pull the entire tree in memory, but we want directories to
+ * show up as having children. Therefore we give directories a placeholder
+ * child and replace their children when they are opened. Placeholders have
+ * TRACK_COLUMN="" and ISFILE_COLUMN=FALSE (so that they don't get check boxes,
+ * lengths, etc).
+ *
+ * TODO We do a period sweep which kills contracted nodes, putting back
+ * placeholders, and updating expanded nodes to keep up with server-side
+ * changes. (We could trigger the latter off rescan complete notifications?)
+ *
+ * TODO:
+ * - sweep up contracted nodes
+ * - update when content may have changed (e.g. after a rescan)
