Can you add to the list
Villagers? It's annoying when trying to change their jobs breaking blocks and hitting them, then an iron golem kills you
And horses?

The newest version adds an entity tag friendlyfire:general_protection which will allow you to protect any mob. Keep in mind that sneaking will bypass this mod. There is also a new item tag friendlyfire:bypass_all_protection which allows specific items to bypass the entire mod as well.

Horses are protected under the "pet" option by default, only if they are tamed.
