Chrome only: Evernote's web "clipping" extension can now show and link you to relevant notes inside your Evernote database when you search Google on the web. If you're the type to forget what you've got saved, it can be a helpful reminder.
It would be nicer if Evernote's "Simultaneous Search" activated in your extension options, offered small previews of the notes themselves, or worked with Google's Instant Search features. But as it stands, showing you that you do indeed have notes tucked away relating to whatever you're looking up on Google could be a helpful reminder not to duplicate your work.
Evernote's updated Clip to Evernote extension is a free download, works wherever the Chrome browser does.
