Colibri is a package that provides an alternative to KDE4 Plasma notifications.
Colibri notifications look lighter and are completely passive: they do not provide any buttons. You may or may not like this.
Since they are completely passive, they smoothly fade away when you mouse over them, allowing you to interact with any window behind them.
They also do not stack each others: if multiple notifications happen, they will be shown one at a time.
