Why
'Status notifyer'-like plugins are preety good... while your contactlist contains just 5, 10, 20 buddies.
Mine includes over 100 persons (family, friends, colleagues, messmates...). And every moment somebody goes offline, 
others come back... So my left side of screen is always flickering with green/red popups ;-) 
Sure, I can turn them off... But I want to be notified when somebody comes back after a vacation, business 
trip, maternity leave ;-)
I found 'Contacts Notifier', but it's really inconveniently to watch for all buddies and their activity... and setup 
a notifyer for everyone who has gone...
So I have thought out to notify just about contacts who were offline for a long time. 
In other words, it works like 'Last seen' plugin, but with notification ;-)
