I've been using this for a couple of weeks and really like it.
Taskbar Shuffle is a small and simple program, that adds a handy new functionality to your Windows taskbar - it enables you to rearrange the taskbar buttons by simply dragging them around. This feature can be quite useful if the order and arrangement of your taskbar buttons is of importance to you. Makes you wonder why the taskbar did not come with this feature in the first place.
