The whole cut-n-paste paradigm is pretty cool, but I think we need a new function: "swap". Swap would allow the user to highlight something and then swap the highlighted stuff with whatever is in the clipboard (a concurrent paste and cut, for you systems people). With our current abilities, it takes a cut, a paste, another cut, and another paste, to swap two items. With the power of swap we could simply cut, swap, paste. Think of all the time we'd save!
