End update, but a better one

Add an end update as people are saying BUT the beginners like me will think it's too hard so I think you should keep a toggle in world settings we can turn on/off to toggle the end update. The toggle can be called End islands with more end islands or if people want a new job boss then mob name toggle can be there so beginners can keep it off if they want to defeat ender dragon only and experienced players who wants end update can turn it on or you could add a biome people could turn on/off an end dimension or another boss' dimension or something
