Launching App Expose From The Dock

After being rather disappointed that the GM seemed to have dropped the ability to do single app expose from the dock, I was amazed when I figured it out, just now. By double tapping on the icon/app you want to expose, you should be able to replicate the old feature. However now, there is no spotlight on the app icon. Hope this helps people who had the same problem as me!
