This isn't pertaining to any specific quest, but I always wanted to see a feature added that would delete active quests from the quest log. There have been quests sitting unfinished (and will remain that way) for years in my log. My deleting the quest from your log, you would (of course), lose any progress made, if any at all. I'm sure I'm not the only person that has gaggles of quests sitting unfinished. It's not like a dire necessity or anything, but just something I'd like to see implemented at some point.
