Fixed a massive bug with permissions, as well as added a version checker for future security updates. I also made it so that lines on holograms will be serialized, so less janky mechanics. In the next version, I will continue to work on making the line mechanic easier to work with.
I'm kinda dumb and forgot to add permissions, meaning any player can just create holograms everywhere. (Which if you can't tell is a bad idea. This plugin is lightweight but not when there's billions of holograms everywhere)
The permission to use the command is: holograms.command. More in-depth permissions will come later.
Added addLine operation for ease of use!
Tested thoroughly on version 1.18.2, but should natively support every version 1.16 and up.
Initial release!!
