At this time, I don’t think any additional settings are available.
This is a feature that I have asked about a few times. I never received any feedback on it. It might be a feature that isn’t used much at this time. With the age of touch screens, smart phones and tablets, I believe it will get used more and more. There are many uses for a “real time feedback” while using sliders and I hope they get this worked out. In my example picture, the Speed can be changed two ways: 1. Click on the value and the keyboard comes up and you type in the value or 2. You swipe left or right on the “knob image” and you can adjust it, but you never know exactly where you are at since the knob doesn’t rotate until you release the screen or the mouse button.
I would love to see this changed/improved in future updates.
