I love working with edge events. With the mouse, no problem: drag the mouse to the edge, and it pops up. So it does with the touch pad.
But with the touch screen, it doesn't. Alas.
I know, there is no actual screen real estate beyond the edge, but doesn't that apply always? Isn't just the acceleration (speed, to be precise) at reaching the last row or column not sufficient to indicate: 'Ah, he wants to cross the edge!'?
