I feel like this should exist, given what you guys started trying to do and what's in the mod so far, but I simply can not find it (feel free to read that as a "wanted: manual" :) ) --
1. "Quest Giver Goals":
I am in a zone. I am a perfectionist and a completist. I would very much like to have waypoints/goals/etc just like I do with quests ("wanted: mok'thor" gives me a point on my map for where mok'thor is, or the area he can be found) for quest GIVERS. For any quests not marked as "completed" in my database. I want to make sure I visit them all, and that seems like the easiest way to. You happily send me BACK to the quest givers/end-points if I've completed a quest (even if it's a quest I got pre-carbonite) so I know you have the locations of these people... :)
2. "Quest Finder" idea:
I'm in a zone. I have one quest to go to DEATHOLME. I want to see if there are other quests I could get to go to DEATHOLM to save me some time. I think something along the lines of a drag-and-select area on the map idea, so I click and drag a rectangle around deatholme, then every quest in the zone that has goals in that area (either quest givers, quest completion points, or mobs/drops in the area) pop up, with the quest line they are in, which quest I have in that, and what I'd have to do next to continue that to get to the point where DEATHOLME is my next goal in that chain. This would help tremendously with zone questing efficiency. :)
