+- One world clock now drives everything with a time of its own: the sky,
+  the HUD clock, satellites, launches and weather. A timeline along the
+  bottom of the screen, shown while one of those layers is on, plays, pauses
+  and scrubs it, with a tick for each launch or frame and a way back to
+  live. Share links made away from live carry the time (samehkhamis, #1512).

+- The timeline brings launches up as the time passes them, offers play
+  speeds from real time to a week a second, and plays smoothly, holding only
+  when the next weather frame has yet to load, with a spinner by the time
+  while it waits. The time rides in a bubble over the handle. The track zooms
+  with a scroll or a pinch, drags along, and goes to the time under a tap, on
+  a phone as on a desktop. Zooming out on the globe stops while the globe is
+  still in view instead of leaving it a speck (samehkhamis, #1513).

+- An application built with fewer layers no longer restores, saves or shares a
+  layer it does not have when a link or saved state from a full build names it
