Heyo again! (didnt want to clutter this suggestion in with the shop suggestion, so I created another one if thats okay)
A datapack / plugin that I would like to see added into the game is the silent mob plugin, which if you arent sure what it does, it allows you to rename the mob “Silent me”, which will then prevent the mob from making any more noise.
It could be useful for decoration, as I’m currently using a hidden mob to help decorate a project I’m working on, but the noise the mob makes can destroy the illusion
Heres some links to learn more about it and how to find it :
