I'd appreciate it in the Current Quests log if there were visual cues to indicate if quests are Storyline, Side, Crafting or Fishing (though, really, those last two are pretty obvious and could simply be identified as side quests). For example, you could use the current yellow gold typeface for Storyline quests and have it be blue for side quests.
Also, it would be nice in the game if the exclamation point over an NPC's head indicated if the quest they have to give you is storyline or side (again, current yellow gold for Storyline and something else for side).
I try to do all side quests, and so my quest log can be somewhat busy and this would help to keep me on track sometimes.
