The feature to play soundeffects and probably music in Nifty was in the back of my head from the very beginning. And today I've added it and it worked like a breeze :)
Well, at first I went for something like adding it parallel to visual effects. Something like that:
...
</onstartscreen>
</effect>
</onclicksound>
</element></pre>
But then it occurred to me, that a sound *effect* is only a special kind of an effect! So I've quickly added a new kind of an effect: "PlaySound" and voila:</p>
...
</onstartscreen>
</onclick>
</effect>
</element></pre>
Feels good. Looks good. Is good. Was very quick to implement too! :)</p>
Sometimes life is good! :D
