Useful to see which functions are executed everytime a kind of event is fired.

Especially useful for events fired often like mouse events.

I'd quite like to see this implemented as well. It would be very useful to be able to tell what nodes have a particular type of event attached to this, but this doesn't appear to be possible in client-side Javascript using the DOM event functions (there was a proposal for 'eventListnerList' in DOM3 - but that appears to have been dropped).

Having a short pause before the event is actually fired would be great for telling if there is an event handler attached or not - you could fire the event, if there is no handler it returns immediately with false, if there is then you can cancel the event and return true (or something to that effect!).
