So recently I have been trying to create very nice, sensible floating islands in minecraft vanilla, which is going fairly well. Like the pictures attached below (one has a special resource pack). My one problem is that the world has to generate with a bottom, my idea for a feature of minecraft would be to create some world that doesn't have a bottom and maybe some more world generation features along those lines. In it's simplest form, a way to generate skylands like people were once able to do. I hope you guys can agree as a bottomless world would be very fun to have an adventure in once again like we were briefly able to.
