Study mode starts on a whole tracing
Before
Turning on Study left the tracing sweeping, so a step about V5 could light an empty box until the sweep reached it. On a phone the bar at the top also held the severity, Play and Share, crowding the title.
After
Turning on Study prints the whole 10 seconds at once, so every step can be read straight away. On a phone the bar holds the title, Study and Share, and Play sits on the tracing.
