On the right side of the Lesson Panel is the Lesson Preview Panel. Here you can preview your lessons' content and customize playback settings. What you'll see in this panel will depend on which lesson type you select from the Lesson Panel:
Enable this option at the bottom-left corner of the Lesson Preview Panel will allow Little Math to override the settings in the Lesson Settings window. If the Override button in the Play Panel is turned on (green light), all the playback settings configured in the Override Settings window will be applied during playback (i.e., the individual playback settings set for each lesson will not take effect).
