This World of Warcraft addon creates a frame that listens for the "PLAYER_ENTERING_WORLD" event. When this event is triggered, the addon checks if the player is currently in an instance using the IsInInstance() function. If the player is inside an instance, it hides the quest tracker by calling ObjectiveTrackerFrame:Hide(). If the player is not in an instance, it shows the quest tracker using ObjectiveTrackerFrame:Show(). This addon allows players to automatically hide their quest tracker when entering a dungeon and display it again when leaving the dungeon, providing a cleaner and less cluttered UI experience.
