• An option to only display nameplate on hostile mobs would be great, cuz nameplates are usually not desirable in the circumstances of animal farms or pets.
• For named mobs, the nameplate will overlap with Vanilla nametag displays.
• Though it may be weird to have Nameplate not displaying mobs' names, adding an option to disable mob name display can make Nameplate more visually compatible with Orderly, a mob health bar mod.

Added hostile only config with 9d13379
The second one is at least with only this mod working
The third option already exists, check the config :)
