You can custom your own settings!!
I have a whitelist Server, but if i want fix server, I cant turn whitelist on because it had already opened. Now I can use that to control which whitelist I want to use.

30KB for something that is vanilla has built-in and you can customise messages in spigot.yml? sheeesh

..
Just why man
you do realize minecraft has built in /whitelist
and you can literally give the permission with stuff like luckperms
and you dont need skript or skript-yaml or anything else
and you want people to credit you for something vanilla MC has.
Please get off this place if you want to post crap stuff.
PLEASE
