I have waited until post Patch 2.1 to write this.
Initially during Beta, we were given the option to select/unselect which quests from the Journal we like displayed on the Duty Tracker. Somewhere along the way the feature got removed, the playerbase voiced disappointment, and I remembered a CM saying it's being looked into.
I really don't want all my crafting/gathering quests (and now daily quests) to be cluttering up my screen when I am not in the right area, especially in dungeons, that wall of text is rather distracting.
I'm somewhat disappointed they decided it isn't important enough to make it into 2.1. I'm writing hoping they would consider it for 2.15 or at most 2.2 maybe?
