When you currently reorder editor tabs we change the background color of the tab you are hovering over, this does not make it very easy to understand where the tab will be placed when the user drops it.

In future we would like to indicate where the tab will be placed by rendering an indicator between the tabs where it will be placed.

Further improvements could include changing the position of the dragged item in relation to the mouse pointer (top left of the editor tab is placed on the mouse) or changing the rendering of the dragged item. The reason for this is that the rendering of the dragged tab can make it harder to see the drop indicator.
