We all know how cumbersome the experience has been while working with left navigation in SharePoint. However, that seems to be changing with the drag and drop support for ordering navigation elements.
It is now possible to rearrange the order of your site navigation elements with the simple drag and drop gesture. Now, no more multiple clicks of the ellipses required to “move up” or “move down.” You need to just be able to grab the navigation item you want to move and drag/drop it into its new location. The re-ordering also works with a sub-navigation location.
