In KDE3, KNotify was already a very powerfull tool used for desktop notification. From the developer point of view this is done in few lines of code. And the advanced user may do almost everything.

Anyway there was still few limitations: The application had no control over the notification once it is fired. No way to add link on the popup or having persistant notification. In Kopete, we had to fork knotify and do some hack in order to add the "chat" link in the popup.

That's why, for KDE4 , I rewritten KNotify almost entirely. It has already more feature than the previous one. I did not anyway redesigned the UI yet. The popup is still as ugly as before, and the configure dialog as complex. But this will probably be improved later.

I've decided to blog about it in order to let developper know about possible stuff in their application.
