Xobni, the makers of an Outlook add-in for a "smarter inbox," have just released a slew of new premium features in a package called "Xobni Plus." For the most part, these new features aim to bring more advanced search tools to your inbox, including the ability to build advanced queries, search within conversations and networks, and create Boolean searches. Also new are auto-suggest and filtering features. The question now is will users pay $29.95 for the upgrade?
