The stylesheet option is there for you to use if you prefer by making your own CSS stylesheet with your own preferences outside of the normal functioning layout of the site. Changes we make to the actual layout of the site can mess up your custom made css that you made. Due to the new site layout you will have to go create a new css with what you prefer as we cannot possibly account for all the different css stylesheets that each indivdual user might have written and make them backwards compatible unfortunately.
