Mail.appetizer (which I wrote about here) is actually being worked on and a new version is available for download. Yes, I'm surprised too — it's been nearly five months since the initial release and I know most of us had just assumed that this project was dead.
The newest version includes:
- Resizable notification window to fit your desktop.
- Custom font for the message body.
- Displays sender's photo signature (from Address Book or .Mac).
- Counter showing number of outstanding messages.
- Shows mailbox name (optionally).
- Notification for every incoming message (no longer limited to the INBOX)
