One thing that was a problem in earlier versions of InDesign was changing the order of the palettes in a palette group. If you weren’t happy with the order, you usually had to pull the entire group of palettes apart and start building the group from scratch. With the huge improvements in InDesign’s interface, the fact that you can now easily reorder panels within panel groups barely gets a mention. In Panel view, click-drag on any panel’s tab to move it to the left or right in the panel group and release your mouse. In Icon view, simply click-drag the icon up or down until you see a blue insert line at the position you’d like it to be within a group and release your mouse. It’s incredibly easy and intuitive.
