I'd love to have a feature that allows you to pin quests, which would make quests appear in the front of your quest book (after the main quest).
I got this idea while questing in Wizard City on my Death wizard. It would be useful if I was able to pin the main questlines for Colossus Boulevard and Crab Alley, so they don't just blend in with all of the other side quests. And it wouldn't just be useful in this instance. When I am doing side quests, I focus on doing one or two at a time, and it would also be useful to pin the side quests I am focusing on.
