That fansite has one for almost every world. It doesn't show which ones you did or are missing, but if you have a quest in your quest log file, you can find it on that world's particular quest tree, and it will give you an idea of where you are in the storyline.
i want to see a "completed quests" section in my spellbook. it's hard to know what you've done and what you haven't. also a little "side quest" marker would be nice so i can see which quest i need to do versus what is just a side mission.
