Hi. I've been able to understand the updates to SS3, and wanted to show the minor updates I've made to the cms attached. Notice the ModelAdmin icons, and the change of the Silverstripe Logo in the backend. I also really like taking advantage of the ToggleCompositeField for my multiple tabs.
Anything else that I can customize? I'm not really sure if there is a use for CMSfields_forpopup in SS3.
