spigot.yml has two options relating to sounds in-game: "wither-spawn-sound-radius" and "dragon-death-sound-radius". These are configurable due to their nature; they play globally for all players and can be quite jarring or surprising if you are nowhere near the event happening.

There is another sound that plays globally for all players in the game: the sound that plays when a player successfully activates an end portal by placing the last eye of ender into the portal frame. This sound is very loud and can be quite surprising to players who aren't expecting it, so my request is that this be made configurable like the other options.
