I still love the idea, so I'm adding this to the planned features list:

* let users control which apps can actually send notifications to them 
(with block/ignore/allow/limit buttons)
* let apps provide a relevance/importance level (like logging levels in 
* let apps provide notification classes, so the user can decide what 
kind of notifications of a specific app he/she wants to receive...

...but as this is slowly becoming sorta overkill, I'm not sure anymore 
if notifications should be integrated in OC core / distribution. Any
