Comment 2 for bug 607769

Hi Mark, in the prototype we implemented it differently, we tracked the movement of the mouse to get a direction when the cursor enters in the launcher and project it to the centers of the tiles to guess the one the user is going towards to. In this case I would probably argue that the icon should be centered. But my understanding is that currently we can't track mouse movements outside the launcher, so I guess that we have to go for a simpler solution like the one you are suggesting.
