• Put literals in a variable.
  return "Todo list data load completed. Task list size: "
• consider more conventional names. Perhaps also shorter, if possible.
  
  notifySaveLocationChange instead of private void indicateChangeSaveLocationRequest(String location) {
  
• Thats a mouthful! public void handleChangeSaveLocationRequestEvent(ChangeSaveLocationRequestEvent event) {
  
  Are you doing this to avoid a header comment! It has other side effects.
• Tests not written properly. Follow convention. One method per test case. We want to know what exactly failed when a build fails. Name test case according to the convention taught in the earlier tutorial.
