Missing:
 - repaginate YUI dialog

This functionality is currently in Quiz Edit tab, but reportedly is not known about by many regular users.
 
Described in the spec at http://docs.moodle.org/en/Development:Quiz_UI_redesign_-_Design_specification

    * Keeping track of any new and modified functions and seeing about the feasibility of unit testing http://docs.moodle.org/en/Development:Unit_tests

Does this need a new cabability? I guess not.
