JavaFX RangeSlider Control

[Sverre Moe]

I had an idea for a new JavaFX RangeSlider control.
Based on this Javascript range slider I found which looks amazing. It would
be great to have a similar range slider for JavaFX.

I discovered that ControlsFX does have a RangeSlider, though rudimentary
compared to the Javascript RangeSlider.

Perhaps the ControlsFX RangeSlider could be extended with an additional
properties and Skin to support similar behaviour and look as this
javascript control.
Mouse dragging of the range (not just the thumbs).
Showing thumb text boxes with the value (editable).
Having vertical thumb lines instead of circular thumbs.
LocalDate/LocalTime RangeSlider instead of integer values.

Is it feasible to improve ControlsFX RangeSlider this way?

I may be way over my head here, as such an endeavour currently is beyond
me. I have never before made a custom control of such complexity, just a
few simple controls. I started a project for experimenting with custom
JavaFX controls, currently I have only two very simple controls in it.
