When we make mouse over at the icon, it will come out and turn into big size but it is depend on what effect that you choose for your icon. Me, I like to see that icon turn into big size.
I just remove all icon like My Computer, My Document, Recycle Bin and others from my desktop and put inside ObjectDock bar, so my Desktop PC will become more clean. New version for this software include Start Menu application, so from ObjectDock we can access start menu. We also can add some widget like weather forecast, temperature and clock animation.
