In all new and improved star menu specialists can be grouped by type. Well done. There are adventure specialists, explorers, and geologists. They seem to be sorted by name in these three groups. What is missing is a fourth group, expedition specialists. Now they are sprinkled (at least in my star menu) among other specialists. Marshals hang out with regular generals, and suppliers mingle with the explorers. They should make their own crowd.
Actually, there should be even more types. Can't confirm right now, but it seems there are only two types that make for instance "explorer supergroup": regular explorer, and all other advanced explorers. But there should be more than just two types: Experienced explorer, Intrepid explorer, Lucky explorer, Savage scout, Explorer. When some of them are named they should not wander out of their type group.
