Just a mere quality of life suggestion. Could we have the quests be re-organized by worlds. Where each world has a its own sub tab for quests. It would be much more convenient, rather than having to scroll through, to find quests in the world you're currently in.
You have a good idea here for sure, but if you're looking for side quests to complete, watch for the little green arrow to appear on the quest goal, it shows you the closest quest to your current location.
