when a horizontal slider or live.slider has Mousing Mode set to relative, slider knob / triangle is increased or decreased when touching the slider (not dragging, just touching down)
If I touch the left part of the slider, value is decreased, if I touch the right half, value is increased.
inc / dec factor is proportional to the distance to the center of the slider.
This issue is only in Mira app in iOS, it works as expected in MiraWeb.
This *may* be useful in certain case, so this could be a cool feature, but actually it looks more like a bug that make horizontal slider in relative mode unusable in Mira.
