I would love to define the size variation of the Blob brush with percent instead of pt.

It´s pretty anoying when I´m painting with e.g. 6pt brush and a size variation by pen pressure of 3pt ( 50%) and after changing brushsize to 3pt the pressure variation stays at 3pt. So i have to manualy adjust it to 1 or 2 pt.

It would be great to give it a percentage so I could define it maby with 60% to have the same feeling how the pen pressure effects the brush size when scaling the brush up and down (there should be shortcuts for scaling the brush!).
