Display unread Mail.app sender pictures on desktop.
iFaces is small Mail.app utility add-on program that will display unread mail's sender pictures on your desktop. It helps you determine if you need to actually open Mail and read the message (or continue working on something else). Inspired by the X11 xFaces program, this Cocoa driven program should make life easier--well, at least more chock-full-o-information on your desktop.
What's new in iFaces
Global Transparency Option Added in preferences.
Customizable Unknown Sender Image.
Domain Database of images added. This nice feature allows you to customize iFaces to display an image per domain if the sender is not in your address book. For example, if you want to know when you receive email from someone at cs.jhu.edu then you would add an entry with a picture to represent this domain.
The window location does not move when new mails are received or read.
