Jumpcut keeps your clipboard around a little longer.
One of my biggest problems with the “clipboard” paradigm is that it only holds on to the last thing I clipped. I’m forever forgetting that I just clipped something I wanted, and haphazardly replacing it by copying something new1.
Jumpcut gives the OS X clipboard a healthy sense of history. It’s a simple little menu extra2 that keeps track of a configurable amount of recent clippings, just a hotkey or a mouse click away. If the top of the screen is too far, you can hit ⌃⌥V to pop up a bezel window that pages through all your recent snips. This slick little app has become an indispensable part of my workflow.
