On-screen controls help
Both the 2D and 3D views now have a built-in controls overlay. It's off by default — you'll just see a small H : HELP marker in the bottom-left corner. Press H to pop open the full list of what every key and mouse button does, and H again to tuck it away.
Fog
The old fog started so far away you basically never saw it. It's now proper exponential atmospheric fog that builds up gradually with distance and blends seamlessly into the background — distant geometry softly fades into the horizon. Toggle with G.
The camera remembers where you were
Leaving and re-entering 3D used to dump you back at the start every time. Now, when you return to 3D, you pick up exactly where you left off (position and look direction) — as long as that spot is still inside a sector. Loading a new map resets it.
