Request: QSlider Markers with Values

[RotemBot]

This is actually a two-part request -
First, can you make it possible to set markers on sliders with step 0 for value, and a different step size for markers?
Secondly, can the markers have a label displaying the values they represent?

And, bonus request, it would be really great if hovering over the slider could trigger a tooltip label with the hovered area’s value.

Thanks!
