The RotoSlider proposed by the AntTweakBar library allows rapid editing of numerical values.
To modify a numerical value, you just have to click on its label or on its roto button, then move the mouse outside of the gray circle while keeping the mouse button pressed, and turn around the circle. This will increase or decrease the numerical value depending on the direction you turn.
The two grey lines depict the min and max bounds.
Moving the mouse far form the circle allows precise increase or decrease, while moving near the circle allows fast increase or decrease.
