Yes, you want to have the cross views. Navigating across (portals). Down (in time). Nested. Calculated relationships. I want a tree view of projects.:))
Sometimes a "dump" for a huge number of profiles is fine until sub projects are defined, if ever. I mostly don't know the battles my American Revolutionary War ancestors fought in. So until I find it out, the "umbrella" project (Wikipedia portal concept) is really helpful.
