Yes, my bad. I do have TaskHud, I was just thinking about a Taskhud, BoxHud mashup. So instead of seeing only one char at a time, I could have a table where I selected "Quest", then it listed each char and the step status. Maybe I'm too greedy.
I had the same issue with taskhud, and I have been working on a YALM/Taskhud mashup that has an easier way to see who has what quests (did they all really talk to that NPC or was the rogue hiding and drunk) and then maybe a way to detect the necessary quest items at loot time, and distribute them without getting into a loot rule for everything. Taskhud does a bangup job of refreshing and showing me who has done what, but the refresh tends to change the character selected, and some other weird behavior. I drive from my ML with my other windows only minimally visible as well so I feel your pain, and in some cases, I have as many as 13 characters running at the same time.
When the servers come back up I can get you a screenshot of what I have going for the task piece which is working pretty well. It is baked into the YALM bastardization I am attempting but I think it could be split out. The loot piece is whipping my ass pretty good but I am learning a lot as Claude and I work through the most recent dumb thing I broke or told him to break.
