Fabricating for a Function

On my bookshelf every time I need to get a video game or a textbook, I end up knocking the shelf and everything falls all over the place. You can see in the video that there isn’t anything on the shelf but there usually is a ton of books, markers, and binders I’m just in the process of moving right now.  Also, I have a charging cable for my Xbox controller that always falls behind the bookshelf of just hangs over the side and looks ugly.  What I want to do is have some sort of bookend that on the other side of it will have little hooks to hold a controller and some sort of holder that will prevent the charger form falling behind the shelf. I also want to be able to have the controller sitting there charging without having to remove the controller or the charger from their places. (The video is uploaded on canvas)
