Humans only

Is there a way so the plugin can show a player killing a human only? not a humain killing an animal?

No it's not, the options involve removing every single entry that includes "VictimType: Animal". That's not an ideal solution, should be possible to either set each category you want to false, or have a global option disabling all animal kills.

With config files like these, where you use arrays and objects with a pretty decent amount of data, then removing them to disable it, is never ideal, as re-adding it becomes a pain.
