Taskbar++ (translated page using Babel Fish) is a great utility, which I have been looking for for quite some time. It lets you rearrange the buttons in the Windows taskbar (assuming you’re not using Windows’ “Group similar taskbar buttons” feature).
I’ve always wanted this ability. It’s very comfortable for me to have the taskbar buttons in the same order all the time, but sometimes a window crashes and to get the buttons in the same order I have to close and re-open the windows in the order I like.
I guess Microsoft realized the need for this feature as, for all I know, it will be available “natively” in the next version of Windows, Windows Vista.
