A quest journal that shows your progress within quest chains in a simple and easy to follow manner, showing not only your current quest but also all the future quests in the line, how they all connect and other quest lines they lead to or require.

Quest lines are now packaged within separate addons per expansion:

BtWQuests: Dragonflight contains the leveling campaign as well as the side quests for each zone along with a few max level quest lines
BtWQuests: Shadowlands contains all leveling zones, covenant campaigns and Torghast unlock (Included by default)
BtWQuests: Battle for Azeroth contains all quest lines including the leveling zones, War Campaign, and 8.2 and 8.3 quest lines
BtWQuests: Legion contains all major quest lines for Legion, including class campaigns and story quest lines
BtWQuests: Warlords of Draenor contains the initial garrison quest chain aswell as the shipyard questlines along with the major quest lines for leveling zones
BtWQuests: Mists of Pandaria contains the major quest lines for leveling zones in Mists of Pandaria
BtWQuests: Cataclysm contains the major quest lines for leveling zones in Eastern Kingdoms and Kalimdor
BtWQuests: Wrath of the Lich King contains very early versions of the major quest lines for leveling zones

Known Issues

Currently opening the quest log from within BtWQuests and then opening and closing Edit Mode will break dragon riding keybindings next time you mount until you logout or reload the ui. I've not found an alternative way to open the quest log that doesnt cause this.
