About Shu
This application collects information about your email inbox – specifically, the number of unread messages – and displays it in a small notification window.
That window floats above all the desktop windows (even above the screensaver), can be moved by dragging it around, and launches Mail.app when double-clicked.
Questions
Q. Why does it only display an exclamation point?
A. The Mail application must be running for Shu to collect the information it needs.
Double-click the notification window to launch Mail, then hide or minimize it.
Q. How do I quit?
A. Right-clicking on the notification window will show a menu. That menu has a "Quit"
option.
Q. Does it work with Thunderbird (or other email client)?
A. No, only Apple Mail.
Q. What does it look like?
