Is there any way to make "unOBTRUSIVE notifications" UNobtrusive?

[Juan R. de Silva]

I'm still trying Ubuntu 12.04 in hope that at least some of the most 
unacceptable for me things would be cured. Default NotifyOSD behaviour is 
one of them.

Google brings tons of searches about how to get rid of notifications 
completely system wide, how to get rid of them for a specific 
application, etc.

My problem I do want to have them for every single app or service as per 
default. However, I DO NOT WANT that damn bubble to stay there after I've 
read the message preventing me of working. It is extremely distracting 
and OBTRUSIVE to wait until it finally disappears.

I run across "brainstorming" (?) on Ubuntu Wiki. Well, in the meantime 
wizards are thinking hard, does anybody knows some dirty workaround that 
would enable a user to close the bubble at his/her own wish? Or the only 
solution is to shutdown NotifyOSD completely?

Thanks.
