A while back I threw together a quick brainstorm about how maybe we could improve Live Bookmarks. Today (via Lifehacker, the most useful site on the intertron) I discovered the LiveClick Firefox add-on. It’s not perfect, but it does give you the ability to “Mark All Items Read”, and a few options about what that means. Very cool. There’s room for improvement to be sure, but I think this is a great start at extending Live Bookmarks.
Update: There’s more information over at LiveClick’s MozDev project page. This is good stuff.
