The Unity notifications (notify-osd) are very much useful and nice. But It seems I can't close them after I get notified. They get blurred when I hover mouse over them, but they don't close. Which is sometimes very annoying.
I Googled about the matter and it seems, there is no way to close them until now.
Can I at least control their notification display time? (If I can close them, that will be lot better). I think, It will be easy by changing some of their settings file.
Note that, I am using Ubuntu 12.04 with Unity, specifically Unity 3D.
