gbox_applet is a GNOME applet which monitors several mbox-type mailbox files. Each mailbox can be assigned to a priority between 0 and 2 and it can have its own time interval for checking. For each priority there is a different icon. gbox can also count the mail in the boxes and show the subject/sender of each mail in the applet's menu. A tooltip shows a summary of the information in three different kinds.
