Doors that open, and zones lit the way the old ones were

Doors. A door drawn into a zone model stops being wall, and opens when you click it, which sounds small and touches everything.

Beaconhold, and a way to build zones that does not weld the doors shut in the process. A zone model now arrives exactly as drawn, with its detail levels the right way round and its leaves found in one pass instead of several.

Light. Zones can be looked at properly and lit the way the old games lit them, which does more for the feel of a place than any amount of geometry.

Two small corrections: arriving by zone transfer always says who you are, and a zone you arrive in is not a zone you arrived in some time last week.
