Works for WoW Classic: Mists of Pandaria & TBC Anniversary.

Tired of logging into your alts to see which ones still need to complete their legendary quest?
Not being able to see an alts current quest log while logged into a different one can be annoying.
Quest Tracker is a very simple addon that displays a menu of every single quest in your quest logs across all your character alts that are complete or incomplete! For every single character alt you've ever logged in to, it is being tracked in this menu no matter how many quests or alts you have. As long as the addon is active when you login and there's a quest in your characters quest log, it will be displayed in the Quest Tracker menu. Anytime you login it automatically adds all the quest names in your quest log and the characters name to the menu for the current character you are logged in on. It will remember every quest in your quest log for every alt on the menu until the quest is completed or abandoned and no longer in your quest log.

Have multiple characters that are on the same quests and want to track their complete/incomplete status? No problem! It will remember every quest that all your alts have in their quest logs! If one of your alts has already completed that quest it will also be displayed in a different color in the menu as completed! No more needing to swap from toon to toon to see if your alt has already completed that quest!

Does not track the status of quest progress or items required to complete quests.
(use your normal quest tracker for that).
It only tracks the quests currently in your logs when your character is online.
If a quest is abandoned or completed and no alts are currently on the quest it will be removed from the list.
