There should be a value in to show the selected gradient position in qt quick designer properties window when try to edit the gradient of color filling.

When I change the rectangle colour mode to gradients and try to modify the gradient, I can only know a probable value of the gradient. I think in some situation user need to know the actually position of a gradient and he have to change to editor mode and modify the value in code. This is inconvenience. So I think if there is a label or an edit box to show the position of selected gradient is more better.
