I'm hoping, that with the greater emphasis on more factions and fauna, that the permission tab becomes much more complex. It is already too simple for what players want to do. I imagine a menu-tree structure would add sufficient granularity. I hope there will be a search function also, because I'd like to see the permissions tree go all the way down to an individual member of a faction, with creatures being members of a pack, flock or similar group that is functionally a faction.
This means you would be able to do silly things like allow a single space-lion in the sirius 243 pride (procedural faction # 423845) on a planet in 20433, 83475, 39635 to have permission to spawn your latest titan. However, such a granular permission system would be useful for sharing something with actual players.
