Sort by Direction is added to the existing sort methods:

By Name – sort selected objects alphabetically.
By Distance – sort selected objects starting with the first object chosen to the next closest object for the remaining selections.
By Size – sort selected objects based on length, surface area, or volume. Objects that do not have these parameters do not get sorted.
Reverse Order – reverses the order of the selected objects.
By Type – sort the objects by Feature Type in the order found in the Measure toolbar.
