"Organize taskbar buttons with ease using this utility. Drag and group or ungroup them as needed." (21 words)
To move buttons, just hold down Shift and drag them around. If you want to create a new group, all you need to do is Ctrl-Click a single button and add a name for your new folder. You can opt to enter anything, but if you don't have a name in mind, the default value should suffice. Once you press Enter, your new group will be ready to use.
Bear in mind that Explorer tends to ungroup folders with only one item soon after their creation, so you should add more items quickly. If you want to include more buttons to a folder, hold down Ctrl and drag them onto the respective group. This works for both custom and normal groups, so you have the freedom to choose. You can even merge two groups by dragging one onto the other.
Finally, if you want to undo a group, all you need to do is Ctrl-Click it, and it will be ungrouped in no time. With all these functionalities, this utility can make your work more efficient and help you keep a more organized desktop.
