Ayatana Indicator for viewing recent notifications

 An Ayatana Indicator applet to display recent notifications sent to a
 notification daemon such as notify-osd.
 .
 Using Ayatana Indicators Settings in the desktop environment's control
 center, you can blacklist certain notifications, so that they are not
 shown anymore by the notifications indicator.
 .
 Ayatana Indicators are only available on desktop environments that
 provide a renderer for system indicators (such as MATE, Xfce, Lomiri,
 etc.).
