This feature could be something like Whistle/Unwhistle for wolf, cats etc and make them independent but for Llama, Horse, Camel, Donkey, and Mule it could make them Follow/Teleport like wolfs.

Player could also change the pet's mode to indy or follow mode individually just like for wolfs, cats etc by sneak clicking.

Thank you for making such a unique mod btw🙂

Hm... not sure if I particularly like that idea *ahem* sorry, I mean: NOT SURE IF I PARTICULARLY LIKE THAT IDEA!

Jokes aside,
the follow or teleport behavior in particular is an easy way to lose your pets/tameables. If you e.g. fly around with your elytra, it may look like they teleport to you - until they suddenly don't, and now they are lost, potentially forever.
I know I lost pets that way, so I'm not keen on adding that behavior to even more mobs.

I get that if you have lots of horses etc you may want to move them more easily, but follow/teleport behavior would basically allow to "summon" them from large distances, which I definitely do not intend (even if it sounds cool).
Llamas in particular already have caravan behavior too, where if you leash one, others will follow in a line.
I'm pretty sure there's mods out there that allow chaining together mobs with leashes to essentially make your own caravan, which I find a lot more appropriate of a solution.

On the technical side this also seems quite iffy, because I'd need to change the mobs one by one to add the AI follow behavior (and potentially change around goal priorities), so it wouldn't work with modded mobs out of the box.

I didn't really "make" the mod, it was originally lizin5ths'. I'm just continuing it after they gave me the keys.
