1. Console creation
   For admin users, it is essential that holgrams be able to be created from console, and not just from a player-context. To do so, a command like /hd create <name> <world> <x> <y> <z> [content] would be a godsend.

2. Chat output-message suppression
   It'd be preferable on a production server to be able to suppress chat output from the plugin. Way too much 'process text' spills into that space. Server admins would prefer to not burden players with that irrelevant-to-them information.

Thanks.

Would a console entry such that you could add a hologram from console /hd concreate <name> <world> <x> <y> <z>) suffice? This would allow the creation via console vs player-context but then use the normal console commands to edit/delete

I would like to know the context of this use case and the reasoning. Why is the output shown to players? Are you trying to use commands in scripting plugins?
