I will definitely have a look at it when I will add te Amiga decorator :) btw, how doesthe new API play with the different decorators? They still have a "Clicked" method doing different things, that I'd have expected to move away. Is the behaviour part done afterwards and modifying the result value of Clicked before taking any action ?
