	Sure. I'd like to get as much of this as possible into the spec. KDE
already have guidlines that are very different from what I'm proposing.
So, we may not be able to come to agreement on all of it. In any case,
also having this in the HIG is a bit handier for application developers.

	That's a bug that needs to be fixed - its the same bug as "I made my
panel bigger and when I made it smaller the launchers were in the wrong
place" and the many other variations of that .

	That's a given. Not all events are important though. And thats what
this thing is for.

	Yes, its a bug and it will be fixed.

	Thats what I mean.
