Evernote is a great way to save links for later reference, and a new update makes the service's web clipper extension for Chrome even more useful. Now when you save a URL the tool uses a new "smart filing" feature to help you keep things organized. So if you regularly put links from Amazon into a notebook called "shopping," for instance, Evernote will recognize this and suggest a notebook and tags based on your history. The updated extension also lets you add clipped pages to notebooks you're currently sharing with friends, which should make group research projects a bit less annoying — though this feature is only available to premium subscribers. The newly updated extension is available now from the Chrome web store.
