Xobni is a free program that adds a sidebar with a slew of organizational functions to your Outlook. Principally built around organizing your Outlook data around people (similar in many ways to the Gmail model), Xobni provides a quick way to view threaded conversations with other people, view exchanged attachment history, view contacts you might have in common with another person, perform "lightning fast" searches, view email analytics data, and other functions.
Xobni ("inbox" spelled backwards, pronounced zob-nee) is an add on that aims to provide an alternative way to access your emails and data. Although currently it is only available for Outlook (apparently the world’s most used email client), there are plans to release this for other clients in the future.
É das melhores ferramentas que me passaram pelas mãos este ano, e convido-vos a testarem. Podem sempre dar uma vista de olhos aqui.
PS - Ah, é grátis!
