With the changes made with the pre-patch to the UI - I can not seem to find a way to make low-level quests show up when I simply want to complete entire zones/side quests after the fact. This is a little frustrating as it makes it far more difficult. Might I suggest putting that as an option under the options - gameplay? Please and thank you.
If there is a place to turn that on and off currently and I have not found it, I would appreciate directions on where to find it!
