Imagine we have a heavy time consuming computation inside a Manipulate (which I model here by Pause[.5]):
Manipulate[Pause[.5]; x, {x, 0, 1, Appearance -> "Labeled"}]
In the above interface dragging the slider is tardy and rough due to slow content evaluation. In this case it is advisable to set ContinuousAction -> False so the dragging of the slider is smooth and evaluation happens only on the slider release.
Manipulate[Pause[.5]; x, {x, 0, 1, ContinuousAction -> False, Appearance -> "Labeled"}]
But the numerical labels do not change during this action and we only guessing at what numerical value the slider will land.
Question: how can I make the numerical labels of controls change during slider drag and keeping content static and updatable only on control release?
