First of all, thanks to @jean-emmanuel for creating and maintaining such a fantastic tool!
I have a quick question regarding the range widget - it seems that when I try to move both knobs of the slider it behaves like a single-touch widget with increased precision. Is there a way to turn this off? Can we access/alter the interaction mechanics for each widget? In this case, it would be ideal to grab a range of the slider and move both points at once at the same rate as when moving one point - perhaps someone here has found a solution for this already? Thanks in advance!
