The problem with this is I'm a web dev and I can't really do all my work in emacs. For backend people you can live entirely in emacs. Once you hit the frontend you have to start interacting with a browser. That's why I always get a clipboard manager and have my editor kill (cut) to the clipboard. Then I can hit C-V and get a popup menu (similar to helm kill ring, navigable both with mouse and keyboard) with the last 100 or so things I've cut/copied.
