We are using one of your themes that has left sidebar navigation and the "Overview" article under a folder or category can't be sorted or arranged to the top. Overview is always at the bottom of the navigation list of a category. There is no way to make it first when the navigation is unfurled. I was told by support that only categories can be arranged, but not articles. Can we get a feature for this to truly sort the left sidebar navigation to how we would like it for better UX? Thanks.
