If you are someone who likes to keep your taskbar buttons organised, then Taskbar Shuffle is for you.
Taskbar Shuffle is a small utility that allows you to reorganise your taskbar buttons with Drag-and-Drop support. It also allows you to reorder the system tray icons.
The utility also allows you to close applications with a middle click. This makes the taskbar work like a Firefox’s tab bar.
At the time of writing, Taskbar Shuffle is only available for the 32-bit edition of Windows.
Cost of Tasbar Shuffle: Free.
