As we have mentioned in the past, we have considered collectible reordering for some sort of premium feature to offer in the future. I tested a reordering of Oblivia's lineup 2 - 3 years ago. There are many features and ideas we have considered or may already have in the works. However, implementing certain features on the forum is more complicated than a simple database tweak. One example of how this particular feature would be more complicated than it may seem to be at first is to understand how the collectibles are actually ordered in each post. They're not actually directly ordered by date, which you can see from the date of my rotten turnip. All of this to say, it will probably be a feature someday™.
