Is it possible for a mod to get a list of which quests have already been completed (ie, does the game make that data available)? Barring that, is it possible for a mod to be triggered any time any quest is completed (at the time it's completed)? I'm looking at this from the perspective of creating an automated "completionist" checklist within the game. However, I'm trying to figure out if it's even possible before going any further with it.
