Animal Tracks and Animal Books

What if you could track animals and players? When a player or mob walks on dirt, gravel, snow, or sand, they have a slight chance that they leave a unique track. Players and mobs can see this and follow this if they wish, but these tracks are easily erased by rain, snow, or other tracks. Animal books are books crafted with a book and quill, a feather, and two bones. This book would be like a study book for Minecraft creatures. They would have at least two pages for each mob. The pages would show the mob's health, attack, attack conditions, enemies, size in comparison to players, biomes/habitat, track data, and a space for custom notes by the player. This book doesn't contain data on monsters because that's weird. These tracks and books would be very nice additions to a wildlife update if that is released soon and could help new players learn about the mobs without having to leave the game.

Thank you!
