In MacOS 9, as in previous versions, an application could send an alert by flashing its icon in the application menu, and tagging itself in the pull-down list. This was a very convenient way to discover that you had to do something without the app just forcing its way to the front a la Windows. But when my apps notify now, I don't see it - I have to check each app to see whether anything has happened. Is Application notification still a feature in OS X?
