Improving the function of the loading slider

The current loading slider allows only the possibility of filling a larger or smaller amount of paint, which does not run out while pulling the brush.
Is it possible for the slider to adjust the length of the ink left on the paper (Especially dry)? Partially, this effect depends on the strength of pressure, but it is difficult to achieve good results in this way. The extra smudge of the brush mark allows you to get this effect, but it's not the same.

We have to think about that, how to better implement smudging when painting with a brush.

If I paint on real paper , the length of the brush mark depends on the amount of paint picked up. Smudging in Rebelle gives a similar effect depending on the smudge brush. This effect can be obtained at Artrage. In my opinion, modifying the slider would be a good solution.
