Let's be frank. At almost any point in time except the very beginning, you probably have several ongoing quests in various worlds across the spiral. It's annoying sifting through the pages to find the particular world/quest you want to focus on at that given moment. So, instead of having them all bunched together as it were, maybe we can have a filtering system based on the world the quest is (currently) in.
There's currently a bookmark on the quest for Tutorial Quest Log, so maybe that can be the basis for it with each bookmark having the icon for each world. And if some people are just fine with the way it is, there can be a default "All Quests" bookmark.
