It's pretty simple. Not much to config, unless you'd like. If you find any bugs, please join my discord: discord.gg/mcdevs and @ me to report them. I hope there aren't any, as I've tested this myself, but if you come across one, don't hesitate to report it.
COMMANDS
Player: /rtpqueue
Admins: /rtpqueue-clear (clears the variables, and deletes all the queue data) - mainly used if it gets clogged up, and it ends up breaking. Shouldn't happen often though.
