EarthNow v2.2.0

Release notes

Replay: a way back to now with a choice of speed

Time travel is now something you start and end on purpose. Once a replay is
under way it stays there: when playback reaches the end of the window it holds
on that last moment, paused. Dragging the slider to its right end keeps you in
the replay too. A Now button appears at the end of the top bar while you are
replaying; press it and the globe is back in the present. Choosing another time
window still returns you to the present as well.

A speed button beside the slider plays the window at half, normal or double
speed: a whole pass takes a minute, thirty seconds or fifteen. Half speed suits
following a storm across an ocean over a week; double suits a quick look at a
short window. The speed you pick is remembered.
