Have tested the plugin on spigot version 1.20.5, and didn't experience any issues, so seem good! If you experience any, please let me know.

Added option to disable sound by setting sound: NONE

added one new field in the config.yml. Can view the latest config.yml always at https://github.com/AlbusThePenguin/skyline/blob/master/src/main/resources/config.yml always at https://github.com/AlbusThePenguin/skyline/blob/master/src/main/resources/config.yml

and option to disable particles.

Side note, unless some creative and unique features come along I don't see me adding a ton of features as the good thing about this plugin in my eyes is that it is lightweight but I always welcome new suggestions.
