Allow for the ability to change prefix with color codes, I like to keep the plugins under the same message format and this would make it a lot better!

No longer needed as this is now an option in the config.yml.

can you give me an example of what you're talking about? https://discord.gg/Bh5YDRC

Like when you do /sps reload it says "SinglePlayerSleep SinglePlayerSleep has been reloaded." (with the first singleplayersleep being the prefix). So I could change it to be like "[SPS] Plugin has been reloaded!". with all command outputs having the prefix and define that in the lang file

You can get rid of the double SinglePlayerSleep by modifying the lang file en_US.yml, and removing the leading SinglePlayerSleep in the file. Somehow that made it past my beta testing.
But I need the SinglePlayerSleep part to let me review logs for issues, So I probably will not add a custom prefix. I may offer a config to shorten it to SPSv?.??_?.??.??

I mean sure add a shorten option.. Or allow custom prefixes and make a debug option that dumps everything to a seperate folder kinda like some other plugins. The debug would just display your plugin issues and excludes the other plugin garbage that builds up in console.
