When working in Windows XP, I am a bit obsessive about grouping programs together in the taskbar. Unfortunately, the order that applications appear in the taskbar is determined by the launch order of the applications. This means that users like myself are wasting time launching applications in a very particular order, and hoping that none of them crash or are accidentally closed along the way.
After a bit of searching, I found a great solution for this problem in Tasbar Shuffle. It allows you to drag and drop your taskbar items so that you too can have the peace of mind that comes with always finding Eclipse as the first item in the taskbar.
