      Clear all caches, verify that Moodle UI that uses YUI still works:
      1/ navigation
      2/ groups UI
      3/ enrolments UI
      4/ quiz
      5/ mod chooser
      6/ etc.

      Try doing a 'stress test' using the course features demo and the course editing page. Examine if its better/worse than before.

    Description

      Since 3.2.0 there is a new way to initialise global "Y" instance - SimpleYUI, see http://www.yuiblog.com/blog/2010/09/03/coming-inyui-3-2-0-simpleyui

      Benefits:

      • 100% backwards compatible
      • easier to migrate oldstyle YUI2 code because Y is available in global scope everywhere
      • supposedly easier to understand for JQuery users
      • somehow seems to make moodle UI flicker less during page load
      • simplifies static JS in "M.*" scope and module.js files

      Potential problems:

      • performance - are pages are very heavy, it seems that loading more at the beginning makes page init feel faster, the total time measured seems to be the same
      • encourages different coding styles - it does not fit "YUI.add('moodle-xxx', function(Y) {" much
