Windows 7 includes a new feature which allows you to hover over your taskbar icons, then middle click the thumbnail to close the program (similar functionality to closing Firefox tabs etc with a middle click). It annoyed me slightly having to click the thumbnail, rather than just being able to middle click the taskbar icon directly. The default action for middle clicking the taskbar icon directly is to open a new instance of the program… bit bizarre I think, but whatever.
So, I searched for a piece of software to add that functionality. Finally found a decent, lightweight one after Googling around for a while called 7 Taskbar Tweaker.
I had to install it again recently, and it took me a while to find it again. So this post is for my own reference more than anything! Hope it comes in useful for others anyway though.
Also, if you’re looking for something to do this on Windows XP or Vista, Taskbar Shuffle should do the trick.
