[Usability] Locating the mouse pointer when it is on the bottom of the screen?

[Maurizio Colucci <seguso forever tin it>]

Hello,

It is common knowledge that buttons anchored to the edges of the screen 
are easier to click, even if they are small: it is like the button had 
an infinite dimension along one axis. For example, if you have a button 
to the top edge of the scrren, you abruptly move the mouse vertically to 
the top of the screen, to the very last pixel, and then you only need to 
adjust your pointer horizontally.

For this reason, I believe, Gnome (or at least Ubuntu Gnome) uses two 
panels by default, instead of one: because they can be put at the two 
edges of the screen, exploiting this logic.

The problem is that the bottom panel is not as easy to use as the 
topmost one because, if I move the mouse to the bottom of the screen, to 
the very last pixel, I don't see the mouse pointer anymore! It is 
difficult to understand where I am pointing.

Unfortunately, the bottom panel contains the taskbar, which is much more 
frequently used than the other panel.

Of course I can move the taskbar, but other people may not be able to do 
it, and in general it is a pity to waste a useful edge of the screen.

I thought maybe the problem could be solved by flipping the mouse 
pointer vertically when the mouse is on the bottom edge of the screen. 
What about it?
