When I accessed the quest list today, "Rag and Bone Man" and "Recipe for Disaster" have subheadings related to the subquests in the quests. But even if you click on a subquest, it doesn't matter, since the guide automatically has the walkthrough hidden when you access the page. So when you click something like "Recipe for Disaster - Subquest 6: Evil Dave", it goes to the Recipe for Disaster quest page, but it shows the Rewards section in your window (since that's where the subquest would be located if the walkthrough was shown).

 

 

 

To sum it up, having subquests in the quest list is pointless, unless the walkthrough is permanently shown when you access the page, but then that would ruin the whole point of having the hide/show option.

These entries are there to implement the Quest Checklist and Calculator functions. So, you check off the ones you've done and it properly adds up your total quest points, as well as showing which quests you have left to do on the Calculator.

 

 

 

It isn't perfect, but hopefully the advantages outweigh the rest.
