I'd like to see options added both for hiding quest icons of quests significantly below my level, and also for quests above my level. (The later is annoying when working on low level alt classes. I'd like to use quest icons to find quests I can actually do, not be shown level 50 quests when I'm on a level 18 class.)

I'd also like to see more variation in the quest icons. Currently, they distinguish between main scenario quests, repeatable quests, and everything else, but I'd like to distinguish about six or seven categories:
  • Main Scenario Quests
  • Festival / Event quests
  • Quests within a continuing Side Story
  • Normal Side Quests
  • Side Quests that unlock content or features
  • New repeatable quests (that I haven't completed before)
  • Repeatable quests (already completed one or more times)

(The distinction between those last two is probably the least important, which would bring it down to six if repeatable ones are left alone.) I'd especially like Festival quests and quests that unlock content/features to be more clearly identified.
