Well, it’s finally here. Stack 2.0 has been released in Cydia. Stack is an application that mimics the Stack feature in Mac OS X Leopard, making your icons stack up in the dock. So far, it works as advertised, but a few improvments are needed. Overall, however, it proves to be a very useful application. It’s also very user-friendly. » Cydia- Stack 2.0
