pHD ▪ Manage holograms with intelligence

Dependencies

One of the supported hologram providers must be enabled:
— DecentHolograms
— HolographicDisplays

— ProtocolLib to manage hologram visibility

Soft dependencies

— If Citizens is enabled, pHD ensures that player NPCs do not trigger the hologram visibility logic.
— If LuckPerms is enabled, pHD uses LuckPerms data to populate tab-completion for the permission option.
— If Multiverse-Core or MultiWorld is enabled, pHD loads after, and processes relevant world manager events, to ensure that all holograms in all worlds are registered.
