Per this screenshot: The slider that support scrolling up and down the category/article list is difficult to invoke. It's like walking a tightrope. Unless you position your mouse pointer EXACTLY, it does not render. Not only is this behavior frustrating. But can lead to accidentally moving an article or category to an undesired location. And then you wonder "What happened to my article?"/"Did I lose my article?" I suggest making the slider wider so that it's easier to invoke. And since it's too easy to move an entity up or down, you should require that the mouse pointer be on the blue/yellow/green dot on the left. As an add-on, the platform should prompt user "Confirm moving _______ from _____ to ____." to prevent unwanted moves. Thank you.
