friendfeedClip ( aka ffclip )
A greasemonkey script that inserts a clipboard widget into a FriendFeed page to locally save (cookie-based) FriendFeed entry links.
Links on clipboard can be cleared all at once or individually. The clipboard is scoped to the URI directory path (so, a separate record of links is maintained). There are at least two scopes: base (friendfeed.com/) and rooms (friendfeed.com/rooms/).
