nice preview. just a heads up, finder always goes at the very front which cant be moved or turned off on a mac. just like explorer.exe. and only the stacks/folders and the trash go behind the separator. just for standards but hell, if it looks ok do whatever you want.
Write the text, then go to the effects menu and choose Drop Shadow, choose normal from the Mode dropdown menu and #FFFFFF as a color, enter 50% as Opacity, 1 pt for Distance, '0 pt for spread and 0 pt for size and there you have it! Very easy, isn't it!
