Kwaga BirdsEye is a desktop widget that recognizes email messages that matter and alerts the email recipient when the recipient receives an email that asks for something or requests a meeting, or when the recipient receives an email with a reply to an important email. The desktop application works whether or not the user has connected to email Inboxes. It supports Gmail and Google Apps, free.fr, and Yahoo mail accounts. Up to five accounts may be used. Kwaga BirdsEye automatically detects and prioritizes the people the recipient has already communicated with in the past (a.k.a. "trusted sources").
