They will be coming up with further enhancement so that you will able to use it with yahoo main, Gmail etc. As per them: Xobni is the Outlook plug-in that saves you time finding email conversations, contacts and attachments. After a quick install, you'll see the new Xobni toolbar appear in Outlook - and suddenly information will become much easier to find.
