Reset a setting; sliders that commit as you drag

A setting that is off its default offers to go back, and a range control writes its value as it moves instead of only when the mouse is released — so dragging one previews nothing until you let go, which is exactly backwards.

A setting you had changed gave no hint what it used to be, and a range slider committed its value on mouseup — so dragging one previewed nothing at all until you let go, which is exactly backwards for every setting a slider is used for.

A control that is off its default offers to go back to it, and range controls write on change rather than on release.
