While choosing which species and what traits to display and the list being arranged alphabetically is quite useful, I think some players would benefit from having an event category for those who are looking for a certain vibe and aesthetic or maybe not having to click on each theme to determine where it's obtained

For example, someone who wants to look for pets from the spring events would have to narrow their search to pets from those events regardless of years, instead of looking at the infos of a bunch of pets that takes a bit too many clicks.
