Feature Request: Add numerical values to density and touch point sliders in Preform UI

It might be useful to have numerical values assigned to the sliders in the density and touch point settings in the support section of PreForm. That way, we can better get an idea of numbers that work for certain prints, etc.

p.s. I noticed that the slider drag handles have an empty vertical line in them so you can see behind the UI into the slider bar … is this by design? or a cosmetic issue? This might have been windows only. Didn’t have time to test on a mac.
