Implemented the suggestion of @Lord_Baygon (thank you!)
Added permissions to the plugin. Now, to let players experience UwU mode, they need one of these permissions: uwu.translate.low, uwu.translate.medium, or uwu.translate.high.
Added translation chances in the config based on player permissions (0-100) high-translation-chance: 50 medium-translation-chance: 25 low-translation-chance: 10
Make sure to assign the appropriate permission to your players!
As always, please let me know if you have feedback, suggestions, or bug reports in the thread. :)
