Suggestion: make the "Windows" and "Activities", application icons activate on mouse over

[Sean Brady <sbrady gtfservices com>]

I think that the overview experience might be smoother if you just had 
to mouse over the "Windows" and "Applications" areas in the overview to 
activate the control instead of clicking on it. In other words, I hover 
over "Applications" and I am shown the applications, same for the 
"Windows" area.  I think that the same could go for the right-click 
menus of the application icons on the left side.  I think it would be a 
small change that would improve usability.

Just a thought.
