In the world of browsers, I was introduced the notion of tabs in Firefox which I can rearrange the order anytime by just clicking and dragging. The ability to rearrange the tabs anytime is really handy since it allows the user to arrange the tabs in a logical order that appeals to the user him or herself.
Now, the ability to rearrange windows at the taskbar is made possible by Taskbar Shuffle. A really small program (633kb) with a simple concept: empowering users to rearrange the buttons on their Windows taskbar by simply dragging and dropping them.
I’ve got the program installed (It’s free!). Whoo~ Another productivity booster. Download here: Taskbar Shuffle 2.1.
