+/**
+ * This list offers the option for the code to provide the developer with links
+ * to sort the given categories.
+ *
+ * NOTE: This UI currently does not scale well with large numbers of items since
+ * it just lists all of them. It would probably be nice to integrate a paginator
+ * as well to as to allow the user to move an item in large distances and to
+ * insert an item in the middle. Right now, when you add an item it is just
+ * placed at the end. However, if you want the item to appear in the middle then
+ * you must hit the "up" arrow n/2 times where n is the number of items in the
+ * list. This clearly is not a good setup.
