Accurately see flow rate, line width, speed in preview

I can see these features in the preview however there is no way to accurately tell what the value is e.g. speed may go from 10-300 mm/s but telling is a feature is 10 or 50mm/s may be important but they will all be a similar colour due to the spread of speeds so it is not possible to tell. Can we have a feature where we hover over of click on the preview model to read the actual value?

Use the horizontal slider and the actual values get displayed for each step as you scroll through them.

Brilliant, exactly what I needed - had never noticed the values there before!
