Mainly for multiplayer servers, but a config option to disable a player lassoing another player would be good to stop people from annoying each other and/or dragging people around.

Plus, I think more config options relating to the items and mechanics in general would be good, not just the animal spawns (e.g. changing the copying ability of mimicube cream). It's hard to customize and balance this mod for servers and there are a lot of optimizations that could be done that would make life easier for everyone.
