Given that Horse Buff is no longer being developed and this mod has gained the functions of that mod, I wonder if it would be possible for, at minimum, the horse swimming and bucking prevention, to regain client-side functionality as a part of the mod. I tend to play on vanilla servers, and as useful as horses can be pre-elytra, it's borderline unbearable to use them without the ability to swim. I'm unsure as to how difficult this would be to implement into the current mod, especially with the change to how horse swimming works (requiring space to be pressed/held instead of being automatic like in Horse Stats), but having partial client-side functionality would be greatly appreciated, as we'll no longer have Horse Buff for the upcoming versions and there's no client-side alternative out there.

Horseman has several features that need client and server side. I don't think there is a way to make it work on vanilla clients in current configuration. So client-only version is not planned.
