Developer tool for tracking quests as you complete them... including the hidden behind the scenes tracking quests for objects/mobs.
I use it to work on my HandyNotes plugins, because the tracking quests are hard to work out otherwise.
This provides a DataBroker plugin to display the data.
If you don't have a broker viewer installed, type
/questschanged to show the log.
You can also type
/questschanged icon to toggle a minimap icon.
