Keeping it up to date isn’t too hard. I do indeed have a catalogue (or three), and … sometimes I actually do forget to index a new story. But that just means I go to look for that story later, see it’s missing, and add it in after-the-fact.
It’s by no means mandatory, it just makes it easier to find what you’re looking for when you have a lot of content!
Also, love the story. I thought it was just gonna be a “fluffies die from eating spicy things” story, but nope! Peanut allergy ruining the little guy’s life and he has no idea! It was a good twist showing his mom really did have his best interests in mind.
