Taskbar Shuffle is a neat system utility for Windows that allows you to organize the tasks in the taskbar by clicking and dragging them around. The program is very light-weight. You can choose to have it run at startup and hide in the background (free up some of those icons in the notification area). It has a splashscreen at startup which you can also disable. Another neat feature it includes is the ability to close a window by middle-clicking it (you can do that by clicking on the little scroll wheel on the mouse); this is a feature that is used in many web browsers to close tabs.
