It would be nice if the Slider Node could have a list of real numbers fed into it so the slider can snap to set user chosen increments within the set range for the slider. This would allow say for the slider to be easily positioned at exactly 50%, or at precise 10% increments etc.
I see this feature as having some behaviour options: 1. Snap to List - The slider snaps to only listed values 2. Weighted Snaps - The slider snaps to listed values only when within certain threshold of a listed value, otherwise it can be set freely to non-listed values. 3. Override Snaps Boolean (Default - True) - Allows the listed values to be ignored and frees the slider to be set at any value with its range. Kind of like how holding down in Photoshop temporally turns off snap to guides feature.
