The title bar of a Display contains an icon representing the reproduction mode of that Display, which is playing or paused .

When in play mode, the Time Scale moves toward the future, allowing users to follows real-time values. Moving the Time Scale to the past or applying a zoom does not change the Scale's movement direction.

When Displays are grouped, only one of the Displays is in play mode and the other Displays on the group copy that movement. When removing a paused Display from a group, that Display stops its movement. If a Display is added to a moving group, this Display also starts to move.
