The TrayIcon plugin provides a notification icon in the system's notification area. It can be used to see whether you have unread or new mail, and to trigger common actions.

Here are a few screenshots illustrating the features:

• The trayicon with one new mail. The yellow tooltip is visible when you hover the mouse over the icon.
  
   
   
• The trayicon's menu. From there you can perform the most common email tasks.
