Customize sidebar

Hi. I only use this for following RSS feeds/blogs and it bothers me that I can't customize my sidemenu to only have home/saved for later and Reader. Because of Twitter, youtube, reddit, pinterest is there the Reader is at the bottom and it bothers me that it it not any space to see the blogs im following because of this, like i see maybe only two of them without having to scroll down. I tried choosing in settings to "hide catergories that have nothing unread" but this only hides blogs in Reader and not the categories like Reddit etc that i do not even use. I would like to choose which apps/whatever that is shown in the sidebar to make it more functional.
