Clipboard manager / widget to track clippings and links on desktop

Before I bought my macbook I remember hearing about an app that allowed you to copy and paste links, excerpts from web sites, articles, email or document drafts, to do reminders, etc. on some kind of side panel or blank document for coming back to later. I think it was a fancy-shmancy mac-ified version of a google widget. Does anyone recognize the app to which I refer? PS. it had some other cool gadgets and bells that made it a super-productive, must-have gizmo for those of us who are slightly ADD, slightly obsessive, slightly genius, but who have a hard time managing the many threads and demands of life in the techno-sphere.
