It would be beneficial if we had a prop that allowed disabling the track, so that the component does not slide unless the user drags the handle itself.

I would like to be able to add a bubble to display the current value in the slider:

The current implementation of the Native Slider component allows you to select a value that is between the labels defined for the component(see the following screenshot). 

If, in the above scenario, we have Slider labels like 0, 1, 2, 3......etc, the user can select a value of 1.5, for example.

Providing an option that prevents the selection of a value that is between the values of the Slider labels will be a very nice property for the component. 

Currently, the described scenario can be implemented using the Slider in controlled mode as demonstrated in this StackBlitz example, but having the functionality out of the box will be more valuable for all users.
