One more thing; The cross-class skills are marked as an attribute and a class; wouldn't it be better to add a checkbox at the top if the user wants to see them added to the list (default=yes), and if so, add this as an attribute to the last class in the list, alphabetically after the Z so it will be the very last attribute on the list by default (however, the user can still get it at the top by sorting by attribute in descending order)
This would make me very happy
