Hhighlight selection on grid stack (tweak series)

this is nice to have feature, in grid stack while mouse over an icon, the icon is highlighted,

check this demo video (it also displays the Recent Stack):

in order to activate in the terminal write:

defaults write com.apple.dock mouse-over-hilte-stack -boolean yes

killall Dock

if you would like to turn it off just turn last yes value to no like this:

defaults write com.apple.dock mouse-over-hilte-stack -boolean no

killall Dock

Enjoy
