- the window is laid out as an editor dock: a tool strip (drawn icons) on the
left edge, the Explorer, the 3D view, and a tabbed Inspector on the right
(Selected, World, Environment, Sound, Headset); the timeline and the status
bar run along the bottom
- the old one-piece properties panel is split into one function per tab;
selecting something shows the Selected tab
- the Frame menu is now Headset (and opens the Headset panel); the tuning
tooltip describes the paced walk
