Default design for default groupe home page

The OG Panels has no editable content within admin/build/pages/edit/node_view
something like admin/build/pages/nojs/operation/node_view/handlers/node_view_panel_context_12/content

which means one can't put panels or mini panles in to make a default group design and using og_panels UI only for custom groups.

Any suggestions on how to design a default og home page?
