Something that would be extraordinary levels of usefulness I personally think would be adding the score requirements for every medal in the codex entry for the animal so if it's a new animal for us vets or a new player to the game we could easily learn just by reading about it the animal codex entry.
it would also be extremely useful to have a fur variation list in the animal codex as well like puma would have light brown dark red gray albino and melanistic in the codex with or without rarity either way it would be hella useful
