preview line when using Spline tools

[D.T. Nethery]

Some drawing tools in TVPaint will show a preview of the line when using the Spline tools , other drawing tools do not show a preview , only the red line of the spline , then when you click Enter you see it applied. What is the difference that allows some tools to show a preview before the spline is applied ? I find it useful to see the line before I apply the spline.

My request is that all drawing tools would show a preview of the line when using the spline tools (perhaps this could be something that could be toggled on and off , because it does tend to make the spline tool lag in some cases).

(here the brush shows a preview before the spline is applied)


In the next image the brush used does not show a preview of the line before the spline is applied --

I am hoping that one of the developers could comment if this is possible ? (i.e. the request above: to allow all brushes/pencils to show a preview of the line when using the spline tools. Why do some drawing tools used the Spline Tools show a preview of the line before applying , but others do not ?)
